Hi Michael,

I hope the information that I provided answers your questions.

The output before the attachment. I only initialized for the attachment and same goes to other variables as well.

Hi,

Unfortunately you didn't supply the Is there any chance you can share a small sample of the Payload , that I asked for. The pictures do not help.

I need to see the actions above to understand what actions and trigger are being used, and what is the Get_response_details action and what the data looks like coming out of the Output of that so I can tell why your turning it into JSON , which is at the object level, instead of further down in the JSON so you get what you need.

Please share the before including the Payload Output of Get_response_details, whatever that action is.

Cheers

Hi Michael,

Thanks for your reply.
So basically, this is when the process started. As you can see below,

The output should look something like this but when I clicked on the view document it was empty. Meaning the attachment didnt show up in the view documents folder link.

Hello,

Is there any chance you can share a small sample of the Payload? My guess is since you are getting the body, which is an object, maybe you can grab something a little further down the stack.

What does the Outputs by itself look like? Can you take a picture of the output window after a run and share that?

Cheers
