[The execution of template action 'Apply_to_each' failed: the result of the evaluation of 'foreach' expression '@json(outputs('Get_response_details')?['body/r937608f3b213434d934b8f54adbd7cdd'])' is of type 'Null'. The result must be a valid array.]

The error message is very clear. If you want to use apply to each you have to provide an array. If the array is empty that would be ok but the content you provided doesn’t exist. If this is a valid scenario you will have to check it before or youse coalesce during apply to each.

I am very new to this (at least a few hours ago), so I am not sure what should I update to the condition flow. Could you please assist me or do you have any tutorials for beginners? It really helps me to solve this issue. Thank you in advance.

First of all you will have to check if you provided the correct content. So should there be an array? The second thing is the expression “json”. Why do you use that? What are you trying to do? Can you share screenshots of the flow.

Here is my condition flow. I am looking for an email notification to be sent to the responder. I searched the existing template but failed to find it. So I decided to create one. The array and JSON () are used to get attachments in the MS Form. Hope this is clear. Appreciate your help.

Did you upload files?

Have you checked the flow run history. So when the flow runs you can see the history (where you copied the error message) and you can look at the action "Get response details". Do you find your attached files here?
