ADF/New pipeline: IndexError: list index out of range

Hi,

We are getting the below error when trying to create a new pipeline:

We never had this issue before, it is new. Any ideas how to troubleshoot this ? Thank you

Solved in the end. The problem seems to be that we had an AWS account that was suspended, to be deleted, which was in many of the targets. Was not possible to see from the error message, but for sure, when removing those targets, it worked

I am closing the issue as we found out the root cause on why the error happened. Thank you very much for the assistance
