ExpressionEvaluationFailed. The execution of template action 'For_each' failed

(0) ShareShare
ReportReport
Posted on by Gift 5

I get the following error when I test a flow I've created:

 

ExpressionEvaluationFailed. The execution of template action 'For_each' failed: the result of the evaluation of 'foreach' expression '@triggerBody()?['incidentUpdates']' is of type 'Null'. The result must be a valid array.

 

 

 

Does anyone have any tips on what I'm doing wrong? Thanks so much!

I am trying to implement A recurring playbook that triggers at knock-off hour every day (Mon-Friday), The playbook collects information about incident id , name , description , URL. All the incidents assigned to the analyst, projected on a HTML table and send it to one of my colleagues.

    Hi @Gift,

     

    I had a look at the documentation to see what type of fields are returned in the response:

    https://learn.microsoft.com/en-gb/connectors/azuresentinel/#incidenteventnotification

     

    Based on that I would say to try and use an array like the updatedFields instead:

    triggerBody()?['incidentUpdates']['updatedFields']
