Abbreviated websocket errors mask actual error

[mmzeeman]

The information which is logged for websockets when something errors is so large it is abbreviated. Unfortunately enough does the abbreviated part contain the error which happened. This leads to a lot of guesswork.

Can we change this so it will contain the traceback?

Should be possible, if i remember correctly lager has some options for preprocessing the output. It would help a lot, as this happens more often. If we are looking into this, maybe we can also pretty print the output? (someone did that before, have to find it again)
