The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts
- Talk to the server developer for more info. You can’t get more info directly.
- Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
- Could be intermittent, like if the server database goes down. May be worth trying at another time.
