Is this something to expect? When? Otherwise, wouldn't it be better to just crash?

[thalesmg]

True, I don't think this should be reached. I'll removed it.

[thalesmg]

Actually, no, it may happen if someone does emqx_conf:update([connectors, type], ...). So better to just skip it, as we can't do validation in that case.
