I am testing loki and promtail, using version 2.9.7, but I encountered a strange problem
Here is a demo log

When testing with the --dry-run parameter, you can see that the generated labels and information are normal.
Remove the --dry-run parameter for actual testing and no error is reported.
But when I go back to loki, I can’t find anything. Now I look at the label browser and I can see the labels I pushed.
But I can’t find these logs in Loki. Can anyone help me?
