Dynamic Content is empty/null when using 'When a HTTP request is received'

I've created a flow that extracts data from a Webhook and works perfectly with dynamic content and then I've created a 2nd flow similar to the 1st but the Dynamic content doesn't work at all they are both very simple flows and I can't figure out what I am doing wrong:

Here is a section of the raw data that has been passed into the 'When a HTTP request is received'

:

Chase0_1-1652459198065.png

and here is the output of the e-mail showing the subject as null but it should be the 'dueOn' from the data above:

Chase0_2-1652459312550.png


The e-mail is being sent but as stated it is blank so I am not getting any errors. I am new to this and I'm hoping it is something simple.

I have tried the same in Zapier and it is working perfectly on that platform.

TIA
Chase

Purely going on the above, it's likely that some of the entries that are received are just blank, so you need to put logic in there that says if it's blank, then do this. That way you can either generate a little error stack for yourself to review and plug the gaps, or you can fill trivial data with a placeholder that makes sense.

 

However I'd say that realistically we'd need to see a bit more (all) of your flow edited in to your initial post, plus the actual error that you're seeing. Screenshots of both (with obfuscations for private data) will be perfect, as they'll help people here support you. 🙂

Hey Eliotcole,

thanks for the reply!

In my original post that is my entire flow, its gets info from a webhook and should send an e-mail. As I also stated in the original post my other flow with a slightly different webhook works fine and this particular webhook also works in Zapier.

Also I am not receiving an error I am just getting null information. It sends the e-mail fine but I don't get any of the dynamic content. I will check with the platform runners if the webhook is working correctly but as I can see on the raw data being pulled into the 'When a HTTP request is received' the data is there it just doesn't seem to be going into the dynamic content and as said before its working on Zapier.

I'm not sure what other information I can edit into my original post that isn't already there from the 1st screenshot you can see I am trying to add dueOn into the subject of the e-mail in the 2nd screenshot you can see that dueOn has a date from the data passed in and then on the 3rd screenshot you can see it just says 'null' in the e-mail subject. If you are able to guide me in the right direction of what other information might be useful that would be great!

Hi @Chase0 ,

 

If Dynamic content does not work, maybe you could try to write the expression manually.

In addition, you could try to recreate your flow and try it again.

OK, one of a few things could be off, here, but I think that there are ways to fix all of them relatively easily. But these are still stabs in the dark, if you want to PM me the schema we can double check it.

Make A More Open Schema

Firstly, with your input schema there, make sure that any fields that you want (or all fields) can arrive empty (null).

 

Realistically you'll be fine if that schema is empty, however I see that you're not creating a ton of flow actions to put the logic in the flow. So let's work that schema so that any/all fields can accept a 'null' value.

 

So, quickly check out this answer where you'll see how you can make a field accept given types of response. Here's the dueOn field as an example:

"dueOn": {
  "type": ["string", "null"]
  },

Then your flow will *definitely* run each time, because there's a chance that with null values it might not fully trigger the flow and it won't run at all.

Conditional Logic For Null Values

You should also put in some conditional logic for anything that might be blank something. You can either do this:

  1. Verbose - With Variables and Condition actions that you then use in the email.
  2. Expression - With functions wrapped around those values you're pulling from the trigger.

Verbose Logic

Verbose is my word, here, but essentially this will ensure that if someone comes to this flow in the future, and doesn't understand the Microsoft expression writing language, then they will be able to do maintainance o the flow.

 

Use the Condition action to determine if (for example) dueOn is null. If it is, then set a dueOnVAR Variable to "Due Date Empty" and to perhaps set an emailVAR to change the send address to alert you to an error.

 

Expression Logic

Here you just need to set each field that you care about from the trigger inside an if() function with an equals() function.

 

So, here is the expression that I would use in the Subject field of the email action:

if(equals(triggerBody()?['$dueOn'], null), 'Due On Date Null', string(triggerBody()?['$dueOn']))

I am assuming that the 'dueOn' field is one of the base properties of the input, and I've put belt and braces around that to ensure that it's placed in as text if it exists.

 

Similarly, you could react to any field values that you care about being null with a strong or() statement. So, for example here, I would keep that dueOn expression in the subject, above, but also have this in the 'To' field:

if(
    or(
        equals(triggerBody()?['$dueOn'], null), 
        equals(triggerBody()?['$changeType'], null), 
        equals(triggerBody()?['$description'], null)
    ), 
    'chase@yourcompany.com', 
    'theNormalEmail@yourcompany.com'
)

This example checks the dueOn, changeType, and description, fields, and if any of them are null, it will send you an email telling you about it. I've separated out the lines to make the logic clearer.

 

Obviously with any of these I'm speaking purely via examples, not your literal values, as I don't know the schema.

Incorrectly Set Schema?

Lastly, take a close look at the Schema, when you passed the example data through to it to build it, did it perhaps have something in a field (like numbers only in a field that is usually a string, perhaps) whereby it's expecting the wrong type of information.

 

If I'm thinking right, though, then the flow wouldn't fire ... but still worth checking.

Ever figure this out?  I'm having the same problem.  Maybe I need to work on my handling of null values as well, but my received http request will also provide an inventory# string.  If I test my flow I can see it in the raw output from my http request, but for some reason the very next step doesn't have a value for inventory# in dynamic content when the flow runs.

Did anyone figured a way to fix this? 

 

I am having a Json object that has all its fields filled correctly, the moment I want to use the dynamic content it shows that those fields are empty.

 

Please let me know if you have any idea on how to proceed.

 

Also any idea where the dynamic content is stored so I can explore the expressions?

 

Thank you!

The best way to make sure you know what's going on in the News & Announcements, to blogs you follow, or forums and galleries you're interested in is to subscribe! These subscriptions ensure you receive automated messages about the most recent posts and replies. Even better, there are multiple ways you can subscribe to content and boards in the community! (Please note: if you have created an AAD (Azure Active Directory) account you won't be able to receive e-mail notifications.)   Subscribing to a Category  When you're looking at the entire category, select from the Options drop down and choose Subscribe.     You can then choose to Subscribe to all of the boards or select only the boards you want to receive notifications. When you're satisfied with your choices, click Save.     Subscribing to a Topic You can also subscribe to a single topic by clicking Subscribe from the Options drop down menu, while you are viewing the topic or in the General board overview, respectively.     Subscribing to a Label Find the labels at the bottom left of a post.From a particular post with a label, click on the label to filter by that label. This opens a window containing a list of posts with the label you have selected. Click Subscribe.     Note: You can only subscribe to a label at the board level. If you subscribe to a label named 'Copilot' at board #1, it will not automatically subscribe you to an identically named label at board #2. You will have to subscribe twice, once at each board.   Bookmarks Just like you can subscribe to topics and categories, you can also bookmark topics and boards from the same menus! Simply go to the Topic Options drop down menu to bookmark a topic or the Options drop down to bookmark a board. The difference between subscribing and bookmarking is that subscriptions provide you with notifications, whereas bookmarks provide you a static way of easily accessing your favorite boards from the My subscriptions area.   Managing & Viewing Your Subscriptions & Bookmarks To manage your subscriptions, click on your avatar and select My subscriptions from the drop-down menu.     From the Subscriptions & Notifications tab, you can manage your subscriptions, including your e-mail subscription options, your bookmarks, your notification settings, and your email notification format.     You can see a list of all your subscriptions and bookmarks and choose which ones to delete, either individually or in bulk, by checking multiple boxes.     A Note on Following Friends on Mobile Adding someone as a friend or selecting Follow in the mobile view does not allow you to subscribe to their activity feed. You will merely be able to see your friends’ biography, other personal information, or online status, and send messages more quickly by choosing who to send the message to from a list, as opposed to having to search by username.
