I have a script which creates a new calendar event, however I am facing an unexpected error when trying to execute nlapiSubmitRecord.

Could this sort of error be raised if I've missed out a required field? Generally, when there's a type mismatch or such like it's reported. In fact, usually the script throws up a specific error if there's a missing field.

What other situations could cause such an unexpected error to occur? Not surprisingly it's giving me a real headache, as even stepping through on the debugger isn't shedding any obvious light on the matter.

Thanks in advance for any insights you might have.
