Get error message for the action 'on failure'

Hi, 

I'm trying to set up error handling in one of my flows. I have 'Create file' action and then 'Exacute strored procedure' on failure. First issue i noticed is if my 'create file' failes but the stored procedure is executed, in the run history it still says Flow was succesfull. I don't think thats informative enought - something still failed and it should be visible in the run history.

You can't just say it run successfully, when one of the steps failed...

Second issue I have is that I have the information on which step of my flows failed but I would also like to get the error message flow provides.

It would make life so much easier to have the error message avaliable as a dynamic content... Does anyone had a similar problem? Any ideas on how to work around it?

Hi @olgaoszcz 

 

The action "Create File Failure Event" you have modified the run after settings of this action to run even when the Creaet File Action fails (please click the ... on the action to see the run after settings) and therefore flow carries on the process instead of marking failed because it is being made to move to the next action forcefully when the particular action has failed (makes sense?)

 

The get error message as dynamic content is currently unavailable as a direct action in flow. You can post that as an idea here:

Hi 

olgaoszcz

 

 

I have been trying to obtain the same thing, just simply getting the error message in flow, and sending it to myself.

 

I found it can be done using the actions() function.

In your case the argument of the action function would be 'Create_file' since that is the name of the component you want to monitor.

It will return an object somewhat like this example of: actions('Set_variable_3')

{
  "name": "Set_variable_3",
  "startTime": "2019-09-09T19:46:51.4123218Z",
  "endTime": "2019-09-09T19:46:51.4123218Z",
  "trackingId": "53a0681f-7810-4bbe-9494-a5cdcdeadb0b",
  "clientTrackingId": "08586335800123686594686241510CU42",
  "clientKeywords": [
    "testFlow"
  ],
  "code": "BadRequest",
  "status": "Failed",
  "error": {
    "code": "InvalidTemplate",
    "message": "Unable to process template language expressions in action 'Set_variable_3' inputs at line '1' and column '2677': 'The template language expression 'actions('conversion_to_currency').outputs.body.status' cannot be evaluated because property 'status' doesn't exist, available properties are 'name, value'. Please see https://aka.ms/logicexpressions for usage details.'."
  }
}

So in my case the name of the component I monitored was 'Set_variable_3' .

 

Now in order for you to get just the error message you can say: actions('Create_file').error.message

If you want to check first if the action failed or succeeded you can check the status: actions('Create_file').status

 

You can use these as arguments in the SQL 'Create_Failure_Event' component to store the error message if any.

Or you use these to fire a terminate component that matches the status

 

Best regards,

 

Michel

Hi @yashag2255,

Thank you for your message.

I set up the 'on failure' on purpose only after the create file fails to handle the errors. As i understand thats what it was developed for...  https://flow.microsoft.com/en-us/blog/error-handling/

Therfore I do not understand why the flow 'is successfull' when it clearly isnt, only the erros have been handled successfully...

Consider putting a Terminate action after the Create File Failure Event and set the status to Failed.  That will let you specify an error code and an error message where you can pass on the error message that you have inside the Flow. That Terminate will only run if the Create File Failure Event runs because the create file failed.  The Terminate command will End the Flow at that point (its the end anyway), mark it as failed, and the errror message will be available in the Flow Run record.

Yes! On the blog you can see that the error handling was configured to check and introduce a way that if a particular action is successful move and perform an action and if it is not successful (Timed out, Skipped, Failed) then do a particular action. So once you force the flow to perform actionsbased on the previous ones, the logic is built that we have intentionally added the action and we want to log it that way (example: if the action was successful go and update an item on SP and if it failed then log an error to another list or send an email to someone and then configure a retry and things like that). 

 

As @Pstork1 mentions, you can use the terminate action to generate an error code and show the status if something has failed but you cannot use the output of that elsewhere as the flow terminates at that action. 

 

Hope this helps!

Hi @Pstork1 ,

The Terminate action sounds like a good solution but the Create File Failure Event is not the end of the Flow, it's actually inside the 'apply to each' and I want the Flow to run through the other files even if one of them failed. Also, I want to have the error message as a dynamic content to send it together with the error alert. 

Thanks for your help Smiley Happy

 

Add an action inside the loop right after the action that can fail.  Set the new action to only run if the previous action failed using 'Configure run after'. The new action should set an error message which you can return at the end of the program.  If the previous action succeeds then the error action will be skipped. Make sure to set the other actions after the error action to run if the previous action was successful or skipped.

Thank you @Pstork1, as you can see from my post, that is exactly what I have done in my Flow. Although, this doesn't allow me to pass the error messages to the next action, there is no possibility to get the error message as dynamic content to pass it thought. This functionality doesnt exist and I'm planning to post that in Flow Ideas.

Thanks for you input.

@olgaoszcz 

 

As mentioned in one of the previous posts, the error message action genearted when an action fails cannot be passed further in the flow right now. It is a good idea to go ahead and create that as an idea on the community forum. 

 

P.S. For some reason this has been happening with me, I am trying to reply to a conversation and then suddenly the accept solution button gets clicked so please excuse me for that. Just trying not to do that (happened on a couple other threads too so my apologies)

What I was suggesting is that you create a variable.  Then when the action fails set an error message in the variable as the action that runs after failure.  That would preserve the error for the rest of the Flow.

You can put the result in a variable ofcourse, but I believe the resulting object of action('component_name') will remain available throughout the flow anyway.

 

The action formatting you mention should be there.  The problem is that the question said this was being processed in a loop.  That makes it tough to get back to the specific action that threw the error.  In this case I normally toss the messages into an array so I have all the error messages later.

Ah OK, bad reading on my part.

I saw the sql statement and thought status was to be written into a DB.

 

 

Hi @MichelH and @Pstork1 ,

 

Thank you @MichelH , that was exactly what I was looking for. The error message is supposed to be entered inside the SQL statement and stored in the database. That makes it easier for me to control the flow reliability. Thank you for your help Smiley Very Happy

 

@Pstork1 - You proposed to insert 'Temrinate' action inside the loop which I cannot do after the 'Create a file' because that will stop the flow immediately while I still want it to be able to loop through the other objects and continue the Flow after the loop. I need the error message only inside the loop. I have another 'on failure' later in the flow to pass errors from future actions. But thatnk you for your help and feedback.

"outputs('<action_name>')" function (in "expressions" of dynamic content) can be used to capture the output of the specified action. This can capture the errors as well but only if they are generated as output by flow at runtime. So a new step that is configured to run after an action fails can use this function to capture the dynamic error message.

Error as outputError as output

It looks like MS has changed the error reporting method recently and I am able to pull the detailed error message from an action with

body('<action name>')['errors']

. Unfortunately, I haven't figured out a way to make this statement dynamic - you have to reference a particular action (can't use variables or nested statements).

If you embed the action in a scope you can use 

 

result('scopename') 

 

to get the full error messages from the action inside the scope that failed.

Hi @olgaoszcz,

 

I realise this is a bit late for a reply but just in case anyone searches this in the future and spots this, I believe you can use the outputs expression to pull results of an action - you can then parse that and pull out codes or messages. 

For example:

Kind regards,

Hey Michel, the above solution will only check for a specific action. any idea how to get the error message for any action on the flow. Because most of my flow contains more than twenty actions. so, this is not a workable solution I think
