ErrorCode=InvalidTemplate, ErrorMessage=cannot reference action 'Copy account to ADL'. The action 'Copy account to ADL' is nested in a foreach scope of multiple levels.

Question

Hello,

I have this copy activity inside for each loop and I added pipeline failure alert logic app pipeline to the copy activity on failure.

I'm getting the error message and other details like @activity('Copy account to ADL').Error['message'].

I'm getting this below error now when executing the pipeline:

ErrorCode=InvalidTemplate, ErrorMessage=cannot reference action 'Copy account to ADL'. The action 'Copy account to ADL' is nested in a foreach scope of multiple levels. Referencing repetition actions from outside the scope is supported only when there are no multiple levels of nesting

Can i not use this expression '@activity('Copy account to ADL').Error['message'].' inside the for-each activity. I'm also referencing this outside of the for-each on failure. Is the above error because I used it outside for-each or I can't use copy activity expressions when it's nested?

someone please help

ADF does not allow you to reference actions from inside a ForEach loop if those actions are within multiple nested levels of loops. The @activity('Copy account to ADL').Error['message'] expression cannot be used outside of the ForEach activity when the action is nested within it.

Here are some workarounds :

1. Use Variables: You can store the error message in a variable within the ForEach loop and then reference that variable outside of the loop. Here's a potential approach:
   • Add a Set Variable activity inside the ForEach loop to capture the error message from the Copy account to ADL activity.
   • Use this variable outside of the ForEach loop instead of referencing the activity directly.
2. Flatten the Loop Structure: If possible, try to reduce the nesting of ForEach activities. You can have a single ForEach loop and manage the iterations within a single level to allow referencing the Copy account to ADL activity.
3. Scope/On-Error Activities: Consider using the built-in failure handling mechanisms like OnError or Scope activities. You can wrap your Copy account to ADL activity in a Scope activity and handle the error within the Scope.
