Value cannot be null (docker)

[VampiricAlien]

One day it was working and the next it wasn't. Only shows 3 menu options. I've checked and checked movie directory, that's the right location and docker is set to access the host path and /movies.

Hey @VampiricAlien - Can you try with the latest release and let me know if you're still having issues?

[VampiricAlien]

exec /usr/bin/dotnet: exec format error

The new update doesn't seem to support amd64?

[taylorbobaylor]

@VampiricAlien sorry about that..... Try this one here. Port listening inside the app needs to be 8080 now FYI.

[VampiricAlien]

@taylorbobaylor I was able to test the new image out, thanks for correcting that. Most of the movie posters displayed but downloading for me doesn't work. I got access denied to the path. The container has the same permissions as the movies. When one fails, it stops trying to download others.

Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]

      Failed to determine the https port for redirect.

info: TrailerDownloader.SignalRHubs.MovieHub[0]

      No movie found in directory: '/movies/test'

I don't have that set as the path.

[VampiricAlien]

@taylorbobaylor The following error happens when trying to download a trailer. The trailer file doesn't exist.

Error downloading trailer
Access to the path '/movies/movie-trailer.mp4' is denied.

[taylorbobaylor]

Hey @VampiricAlien can you pull the latest image and let me know if that works for you?

[VampiricAlien]

No longer working, can no longer get past first page.

Your application is running in Production mode, so make sure it has been published, or that you have built your SPA manually. Alternatively you may wish to switch to the Development environment.

[taylorbobaylor]

Hmmmmmm.... I'm running it fine on my Synology setup..... Can you share you docker-compose or docker run command you're using? Did you clear out your config.json? Can you if you didn't?

[VampiricAlien]

For some reason the folder is empty.

On start up

warn: Microsoft.AspNetCore.DataProtection.Repositories.FileSystemXmlRepository[60]

      Storing keys in a directory '/home/app/.aspnet/DataProtection-Keys' that may not be persisted outside of the container. Protected data will be unavailable when container is destroyed. For more information go to https://aka.ms/aspnet/dataprotectionwarning

      Hosting environment: Production

      Content root path: /app

Is there a config file to download?

[taylorbobaylor]

No looks like it started up fine now. Can you share the command you're using to start the container? Or the section in the docker-compose?

[VampiricAlien]

docker run -d \
  --name=movie-trailer-downloader \
  -p 6767:8080 \
  -v /path/to/movies:/movies \
  taylorbobaylor/movie-trailer-downloader

starts up fine but once I press submit I get the error System.UnauthorizedAccessException: Access to the path '/app/config.json' is denied. sane error I posted before.

[taylorbobaylor]

Did you do a docker pull of the latest image before?

[VampiricAlien]

The one updated today? yes.

f55737780db7 updated 3 hours ago

[taylorbobaylor]

Yeah.... I'm not sure... It's like the user you're running the container under doesn't haver permissions to create files or something.... Can you try running as root user or something to see if that does something?

I can't replicate the issue locally it seems.

[VampiricAlien]

Success! downloads trailer, however the quality isn't good. 720P but looks SD?

[taylorbobaylor]

Nice, glad you got it working!

It's downloading the highest quality one available on youtube that it's getting from TMDB API. https://github.com/taylorbobaylor/TrailerDownloader/blob/3b617849bb0a0e7bcbe9d83d2361dbfb0126c233/TrailerDownloader/SignalRHubs/MovieHub.cs#L189

Is it okay to close this issue now?

[VampiricAlien]

@taylorbobaylor Thank you very much for your help. I believe the error was that I had mapped it to a folder.

[taylorbobaylor]

Awesome, glad it's working for you!!! Look out for some updates in the future. Going to make a major refactor 😊
