[John5798]

Describe the Bug

When the plugin settings window is opened. it throws an error "Unexpected error occurred creating progress dashboard" and nothing else except the setting to change the update interval is shown.

Also, the update theme songs task fails midway.

I tried refreshing all metadata for my libraries and also tried completely removing the plugin and residues and reinstalling. None seemed to work or change the behavior of the plugin.

Expected Behavior

A progress and list of movie and show names should have been shown inplace of an error and the scheduled task should have passed without an error.

Additional Context

OS: Ubuntu Linux 24.04 Noble Numbat Jellyfin Installation: Official Docker 10.9.1 Kernel: 6.8.0-31-generic Plugin Version: 2024.514.151.24 Plugin Installation type: Repository

Same thing is happening to me. The weird part is when I first installed the plugin and started the scan, it actually showed me the progress dashboard, but after some time it just broke.

I have created #331 to try to improve the error handling, it won't solve the problem, but it may help me identify the cause. Can you run this build and provide new logs?

Same Unexpected error occurred creating progress dashboard, and I'm not getting any error messages only the usual "[WRN] [21] Jellyfin.Plugin.Themerr.ThemerrManager: Missing from ThemerrDB: "Movie", contribute:"

[ReenigneArcher]

@haloTT100 in that case, the cause of your error is not the same. This issue is due to an invalid json read. Please open a separate issue with relevant logs from both jellyfin logs as well as browser logs.

My server is down at the moment (CPU fans blown). I could test it by Thursday the coming week. Sorry for the inconvenience and thanks for your awesome project!

[John5798]

@ReenigneArcher Hi, I'm back again after a long break. What could I do to help solve the error?

[ReenigneArcher]

@John5798 testing the artifacts from the url I posted previously would help, and providing new logs.

@John5798 testing the artifacts from the url I posted previously would help, and providing new logs.

I'm using the exact configuration specified in the 1st comment but with the provided artifact file installed (v 0.0.0.0)

When opening the plugin settings page, the above is displayed. The corresponding debug log is as follows, https://pastebin.com/Aa5x4cPp

The following link corresponds to the logs and final error when running the plugin from the scheduled tasks tab, https://pastebin.com/v6LKNuVb Hope this helps.

@John5798 thank you!

Please open this file: /movies/Damsel (2024) [imdbid-tt13452446]/themerr.json

And change the content from:

{"downloaded_timestamp":"2024-05-14T00:57:45.808227Z","theme_md5":"a92cfeb9055207dd0f1b46a1c35b5ff0","youtube_theme_url":"https://www.youtube.com/watch?v=NTdE0XgueC0"}}

to:

{"downloaded_timestamp":"2024-05-14T00:57:45.808227Z","theme_md5":"a92cfeb9055207dd0f1b46a1c35b5ff0","youtube_theme_url":"https://www.youtube.com/watch?v=NTdE0XgueC0"}

Notice the extra } at the end of the file.

If it works after that, it means only that single file was corrupted. If it fails, you probably have multiple corrupted files. If it fails again please post new logs just in case.

[John5798]

@ReenigneArcher Thank you very much! The above solution worked! Now both the task and the settings page work without erroring out! Thanks for your patience and for this awesome project. Also, could I now upgrade to the latest version from the repo? Thanks again and have a great day!

[ReenigneArcher]

Cool, glad it's working!

It should be fine to switch back to the repo.
