How do I get debug_backtrace() to fire on the endpoint site of a Deployment process?
note the following: fc661e5c-62de-fa34-2557-0f6f5a2acbfe
and then... General error: 1366 Incorrect integer value: 

the number or UUID is not an integer.

therefore you'll get that sort of error message. I'm assuming deploy has either a bug in it or you've forgotten to run update.php on your DB the FID field is marked in the DB as an integer when it should be a varchar / string field.

Take a look at the schema and see what needs to change. that should at least give you an indication of where things have gone wrong.
