Duplicated Labels

[diegomvh]

Hi @josephwoodward
I recently updated the library and logs stopped coming to grafana.
Investigating I saw that my code for various reasons generates duplicate labels.

HTTP/1.1 400 Bad Request
Content-Type: text/plain; charset=utf-8
...

stream '{app="siu-api", app="siu-statics", username="anonymous", username="dvanhaaster", version="1.5.0"}' has duplicate label name: 'app'

In a previous version of the source code, I think, that this behavior was allowed and the effect is that the last added label prevailed.
The question: Is this behavior correct? Should I change my code?

Thank you

I have (probably) the same problem. When upgrading from v2.2.0(respective 2.1.1.0) to v3.0.1 (Nuget) i receive no more log entries in Loki/Grafana. When i downgrade it works again.

I have a simular problem. With 3.01. I do not get Labels, instead all is send as Parsed Fields.
