.KairosDbRequestException:: query.metric[0].tags[0].folder value must not be null or empty

[vjkoskela]

This may be a non-issue (e.g. simply user error) in which case the right thing happened:

"requestUri":"http://localhost:9415/api/v1/datapoints/query","httpStatus":400,"httpMessage":"Bad Request"

However, it seems like an condition to require folder on a tag, or at least the error message may be misleading or incorrect.

Probably deserves some investigation.
