AttributeError: module 'streamlink.plugin.api.validate' has no attribute 'text'

[JSDA123]

Streamlink installs but no longer works after recently re-creating my tvheadend container.

Streamlink previously worked with the same image Linuxserver.io version:- 62adbebf-ls192 Build-date:- 2023-11-04T15:37:47+00:00

The issue is not resolved after pulling the latest image: Linuxserver.io version:- 62adbebf-ls193 Build-date:- 2023-11-18T15:42:00+00:00

The issue might be a changed dependency in alpine:edge ... so I've waited a few days to see if it is resolved upstream, but so far no joy.

Streamlink installs successfully as usual:

Running streamlink -V returns the expected result:

$ docker exec -it tvheadend streamlink -V
streamlink 6.3.1

However any attempt to use a flag other than -V (for example opening a stream, or just "streamlink -h") results in errors such as:

Thanks in advance for any support you can provide, this script makes my tvh setup so much more useful!

[cgomesu]

is this related to streamlink/streamlink/issues/5681 by any chance? do you also get this error while using other plugins? (it seems you're sideloading a version of the chaturbate plugin which is the source of the error.)

Thanks that was the issue!
