My flow works. It does everything it should, and yet it keeps telling me that it's failing with the above error. This part of the flow is deleting rows from an excel template to revert it back to empty.
Even weirder, is without any changes, it was working fine the other day, then suddenly it started throwing the error message, despite as I said, everything still working fine; the template is still reverted to blank as it should.

Any ideas are greatly appreciated!
