Look how to emit with an error class so we don't have two identical messages for log and error

[TimoGlastra]

Could we not make the error class also emit a log message? I have seem this log and afterwards a couple of times and adding it to the error class would make it more consistent, if that is what we want.

If agreed, seperate PR would be fine.
