Cannot call method 'indexOf' of null

Hey all, after a few hours of operation we are seeing these types of errors in our error log:

It would be nice to get some insight here. Has anybody else seen this issue?

This issue was due to an invalid input validation on our behalf. We called connection.queue(null, [...])

Perhaps, the library could do some validation of that parameter since this does lead to a crash.
