TVDB missing episodes API issue

[iNfRaS0NiC]

Hello,
I am getting this WRN in the log

[2023-08-12 16:54:51.068 +02:00] [WRN] [14] Jellyfin.Plugin.Tvdb.Providers.TvdbMissingEpisodeProvider: Unable to get episodes from TVDB
TvDbSharper.TvDbServerException: Invalid credentials; API Key Required

   at Jellyfin.Plugin.Tvdb.TvdbClientManager.<>c__DisplayClass24_0`1.<<TryGetValue>b__0>d.MoveNext()

The missing episodes are not working is there a way to fix this issue? I have API from TVDB and I am using it in the plugin
Thank you.
