I have the same problem…
Grafana: v9.1.6
Loki: 2.1.0

This is in the new installation Grafana and Loki, but not old installation or upgraded Grafana.

Below my query:

{job="lb-vip"} | pattern `<ip> - - <_> "<method> <uri> <_>" <status> <size> <_> "<agent>" <_>` | __error__=``

I have this in the Latest Chrome and Firefox, respectively.

Is it about bug in latest Grafana (9.1.6) or something else?
Below the result in Explorer

I found it.
not a bug ,just a version question. you need match grafana and loki version.
just upgrade the loki version higher ,it’s fine.

Hi…

I just change the log source to JSON format, and all the query works fine.
Just little bit change of the grafana queries to make it worked.

deeply,the difference between mine question to yours is that i wrote logql with autocomplete worked fine,however, when i wrote it myself what is same like grafana autocomplete but not using autocomlete,it seems like this error.and restful request seems url params ‘query’ was not same,
