Traefik log message about Compression: "mime: no media type"

[mcmaxl]

Hi all,

I have setup Traefik according to Anands latest guide on his blog and its working fine, however I am seeing lots of these log entries:

level=debugmiddlewareName=middlewares-compress@filemiddlewareType=Compressmsg=mime: no media typetime=2024-03-16T21:19:46+01:00

can this just be ignored or is something likely to be wrong with my setup? I couldnt find any related discussions.

Thanks in advance!

Did either of you ever figure this out? I'm having the same error with Traefik v3.3.4

I tried turning off compression for various filetypes, but still get the error.

        gzip:
        compress:
