Error Handling - Run Power automate Desktop Flow

[AdminInfra]

Hello all,

I'm trying to create error handling mechanism(TryCatchFinally) in my working flow:

Basically, when someone says something in a teams chat, a desktop flow it's started and do something, and after that, post back in the same teams chat, that flow it works.

But, sometimes, i literally don't know what happen's in this desktop flow, sometimes the it's a connection error, sometimes it's a desktop flow error, because something changes in the server and because of that, the flow don't start...

The main problem is that, how can i get this error to teams chat again, i try this way with xpath, but only retrieves the error on apply for each context, i need this error here:

XPATH(not working as expected)

xpath(

    xml(json(concat('{"root":{"action":', result('apply_to_each'),'}}'))),

    '//error/message/text()'

)

This is what i needed at most:

Thanks.

Hey @AdminInfra 

You can follow my approach of error handling or logging errors.

Logging of Actions in Sharepoint. [Inputs, Outputs, Final Status, Start Time, End Time], Log Errors. 

There will be different errors many times, so its really difficult to catch the error message. The above approach should be good to catch the error.

Thanks for the help,

I Tried this approach but i can't get the details i wanted, because only show the entire body, and i wanted only some part of this body.

I tried the option of generate from sample, and control c + v that code described in your article, but that thows me another error saying that it's not an array, it's an object, something like that, but in that way, it shows the content of body available to use and select.

Can you paste here what you are getting in result here?

Replace any personal data with test data of there is any.

I will make expressions and give it to you.

My replies are not showing, i don't know why.

Hey @AdminInfra 

So I added your result part in a compose action.

Then used the following expressions to get the error.

outputs('Compose')?[0]?['outputs']?['body']?['error/details']?[0]?['code']

outputs('Compose')?[0]?['outputs']?['body']?['error/details']?[0]?['message']

outputs('Compose')?[0]?['outputs']?['body']?['error']?['code']

outputs('Compose')?[0]?['outputs']?['body']?['error']?['message']

You should use a similar expression. Replace outputs('Compose') with the respective

action name.

These were the outputs for the above expressions:

You can use below expressions too, that will help you when someday the error is in

some different format.

coalesce(outputs('Compose')?[0]?['outputs']?['body']?['error/details']?[0]?['code'],'No Code')

coalesce(outputs('Compose')?[0]?['outputs']?['body']?['error/details']?[0]?['message'],'No Message')

coalesce(outputs('Compose')?[0]?['outputs']?['body']?['error']?['code'],'No Code')

coalesce(outputs('Compose')?[0]?['outputs']?['body']?['error']?['message'],'No Message')

So what exactly this coalesce function will do is, that if it is not able to find these variables,

lets say it was not able to find any output from the above expression.

Then it will show the custom message which is at the end.

So at the end I have written No Code and No Message.

You can replace it will some other custom message also.

I hope this helps 🙂
