Hi all,

I would greatly appreciate some help with a simple flow that has been running into:

The execution of template action 'Apply_to_each' failed: the result of the evaluation of 'foreach' expression 'atta@{triggerOutputs()?['body/attachments']}' is of type 'String'. The result must be a valid array.

The flow is to automate saving the attachments of 4 emails from the same recipient to a SharePoint site.

If the mail already exists in the inbox, maybe you could try as follows:

In addition, here are some links for your reference.
