Crash: 'NoneType' object has no attribute 'translate' when required parameters fields are missing

I'm running into this error when using script-server 1.18.0 and executing a script.

Traceback (most recent call last):
File "src/web/server.py", line 410, in post

AttributeError: 'NoneType' object has no attribute 'translate'

I was missing the "name" of some constant parameter in the script config... A better error message would be good when required fields are missing.
