Apply to Each Error

Hello,

 

I built a flow that has been successfully running for over 3 weeks but - for some reason - it started to fail a few days ago. Not sure what to do.

 

I use the flow to trigger an item on one SharePoint list to be moved to another list and deleted from the first list. 

 

Please help!

Hi @Geyser ,

 

As mentioned by @David_MA , you are not actually looping an array. I'm not sure about which are the data types from you 'Milestone value' and your 'Extension status' properties, but apparently Power Automate is reading them as strings. Also, I'm not sure if it works fine to enter two dynamic contents as input for the 'Apply to each' loop. 

 

You can refer to this article for more information about how to work with arrays, how to iterate its items: http://digitalmill.net/2023/07/12/using-loops-and-accessing-array-elements-in-power-automate/  

 

For now, I recommend you to set the 'value property from your 'Get items' action as input, as mentioned by @David_MA . You can achieve it by selecting it from the dynamic content list: 

rzaneti_0-1692659779601.png

 

If for any reason your 'Milestones' or your 'Status' columns are arrays, you can loop them inside this 'Apply to each'. If this is the case, please share an image of your 'Create item' action expanded, so we can see how are you populating the inputs (please remove any sensitive content from the image).

 

Let me know if it works for you or if you need any additional help!

Hi @Geyser ,

 

The 'Get item' is fine 🙂

 

Just to confirm: your goal is to replicate the exact fields from 'Get item' into 'Create item', right? If yes, just remove the 'Apply to each' and set the fields dynamically in the 'Create item'. For your choice columns, be careful to select the dynamic content containing only the column name itself:

Can you show how you have the Apply to each action configured? According to the error, you are not using an array in the Apply to each action, which is a collection of multiple items. Of course, it seems odd that it would be working for so long without generating this error if that is the case. Check to make sure that the Apply to each is configured to use value.

David_MA_0-1692644102574.png

 

Thanks for responding. It was working great, in fact, it's still working on two other lists. 

 

Here's the configuration. At first i had "ID" there and then changed it to what you see below since I got the error.

Hello Rzaneti,

 

This is the current configuration. I do not have the "value" option in dynamic content, even when typed in the search bar. 

Demo of Flow .png

Hi @Geyser ,

 

It was my mistake: you have a 'Get item' action, but I thought that you had a 'Get items' (in plural) action. only the 'Get items' has a 'value' property, as it returns an array.

 

Could you please confirm if your 'Milestone value' and/or your 'Extension status' properties are arrays? If not, you can just remove the 'Apply to each' allocate your 'Create item' in the 'If yes' block of the condition. 

Hi Rzaneti,

 

The Milestone column has 8 choices that people can use to select the current stage of the project. Extension status is very similar in that it has choices that need to be selected. So, yes, I would say they're arrays. 

 

Considering, do you think I should change it to Get Items?  

Hi @Geyser ,

 

The 'Get item' is fine 🙂

 

Just to confirm: your goal is to replicate the exact fields from 'Get item' into 'Create item', right? If yes, just remove the 'Apply to each' and set the fields dynamically in the 'Create item'. For your choice columns, be careful to select the dynamic content containing only the column name itself:

Hi Rzaneti,

 

I apologize for not being clear. This flow is supposed to take "Completed" (Milestone status) and "Fully Executed" (Extension status) projects, move them to a different list and delete it from the active list. 

 

The Get Item should be the same as Create Item on the new list. Does the solution still apply? 

Hi @Geyser ,

 

As you will keep the 'Create item' action inside the condition that is checking if the milestone status is 'completed' and if the extension status is 'fully executed', this flow design may work.

 

If you have a 'Delete item' for the same conditions, make sure to position this action inside the 'If yes' block. 

Hi Rzaneti,

 

What can I do if the 'Apply to Each' continues to populate automatically? 

Hi @Geyser ,

 

The 'Apply to each' is automatically generated when you fill which field? For Milestone and Extension, are you selecting the dynamic content without the 'value' and 'item', like highlighted below?

rzaneti_2-1693256792770.png

 

 

Hi Rzaneti,

 

It triggers automatically when I put LCO value (list of names). I have not used choices. For dynamic content, I select each column as seen below. Flow community .png

Hi @Geyser ,

 

I believe that it is happening due to a column with 'Choice' data type. I'm not sure about which of your columns have this data type, but if it have only one selected choice, the 'Apply to each' may not be a problem. 

 

If none of your columns have a 'choice' data type, please share the raw outputs from the trigger, so we can identify where the problem is. If you don't know how to access the raw outputs, follow the steps below:

 

First, go to the 'flow details' page and click in one of the previous runs:

rzaneti_0-1693433024793.png

 

Once you do it, you will be in the 'flow run page', which may look like this:

rzaneti_1-1693433024791.png

 

Go to the 'When a new item is created or modified ' trigger and click in it to expand the details. Then click in "Show raw outputs" in the OUTPUT section. In some cases, this button appears as 'Click to download':

rzaneti_2-1693433023948.png

 

It will display a sidebar on the right side of your screen containing this JSON notation (if you had the 'click to download' option, it will open the outputs in a new tab):

rzaneti_3-1693433024318.png

 

Find the "body" property. It is always after the "headers" property. Inside the "body" (and eventually inside the "value" property), you will see the properties related to your List record. That's what we need!

 

Make sure to remove any sensitive content from the image before sharing. You also can find more details about how to access the outputs in Power Automate in this article that I wrote recently: http://digitalmill.net/2023/06/29/how-to-access-the-raw-outputs-in-power-automate/

Hi Rzaneti,

 

You're correct. The 'Apply to Each' appears only with columns that have the choice data type. After adding the values in dynamic content, I end with seven or eight Apply to Each sections. What do I use for dynamic content in this case? This is the major problem I'm having. I've tried several things but I continue to get an error - usually the string error and invalid array as seen at the beginning of my post. 

 

Also, if you could recommend a training on dynamic content, arrays, loops, etc., I would greatly appreciate it. 

Hi @Geyser ,

 

If you are not getting the dynamic content from your 'choice' columns (without the value/item references), maybe you will need to access it via expressions. To build these expressions, you will need to access the raw outputs from your SharePoint 'Get item' action and reference the 'choice' columns (if you share the raw outputs, I can help you to write these expressions). 

 

About the trainings, I usually search for information in the Power Automate official documentation (which not always is enough), and then in YoutTube videos (personally, I find the videos from Reza Dorrani and Kevin Stravert very useful). I'm pretty sure that you can find some trainings in Udemy, but I don't know about their quality. I took this one when I was starting (it is more focused in Power Apps, but it has some very good videos about Power Automate as well) and found it very good: https://www.udemy.com/course/build-solutions-with-power-platform/ 

 

 

A choice column would not be considered an array unless you have it set to allow for multiple choices to be selected. If only one choice can be selected, it is not an array.

I do have some columns set to select multiple choices. I'm still struggling with setting up the flows which are arrays. 

Thanks, Rzaneti! So, I just learned that a column setup with multiple choices is an array, and the reason my flow is failing. What is the process to setup the flow in this case, is there a particular expression I should use? 

I think I have figured out what you are trying to accomplish. Is this what you want to do:

  • When a new item is created in List A,
  • You want to create a corresponding item in List B,
  • Then delete the original item from List A
  • Some of the fields allow multiple choices, and you want the multiple choices copied over to List B

If so, for each field where you allow multiple choices, you will need to create a corresponding array variable. You will use an Apply to each action on each field (not on the item itself) and append the values to the corresponding array variable. You can then use the variable to populate the field in the Create items action.

 

Below is an example:

David_MA_0-1693928718753.png

When you populate the field in the Create items action, click on the button to the right of the field to change it to Switch to input entire array. Note the difference in the icon to the right of the People and Choices fields.
