Watcher Error is Parse Exception, unexpected field

[Mariner191]

Hi,
How to diagnose and proceed from this Error (Parse Exception)?

Thank you!

The parse exception is that isn't not valid JSON. By the looks of it, you need to remove line 215 as it's closing the object early.

Your idea helped. Left "match all" intact, starting at line 215. Progress: No “Invalid JSON” at end of request.
Now however: with "match all" included, Simulation runs, but indicates "failed to execute watch input". Ideas on how to troubleshoot input? Thank you!

3: With State = “OK” (working properly), why then, Simulation indicates “failed to execute watch input”? Thank you!
