Hi,

I am using Docker version from meisnate12/plex-meta-manager:nightly on Unraid.

I am trying to enable MyAnimelist following this guide:

1. Proceed to MAL Auth config on website: Done

mal:
  client_id: 37a***********4
  client_secret: b5fc*********39

3. Connect to docker and run script: Done
4. Script will initiate first OAuth call an provide URL: Done
5. Once redirect to localhost copy/paste url: Script didn't wait and continue

6. Interrupt script, update config as:

mal:
  client_id: 37a***********4
  client_secret: b5fc*********39
  localhost_url: http://localhost/?code=def502002587f7e04e*********332

7. Relaunch script and see if that did work:

I am also experiencing this bug which makes it impossible to authenticate MAL.

[chazlarson]

As a workaround I have a couple small scripts here that do just the MAL and trakt auth bits in isolation and produce the YML ready to paste into your config:

That worked great, thanks!

That worked great for me too, thank you!

new MAL auth method added in 1.17.2

[linxchaos]

I'm sorry to re-open this, but I'm still having this issue on 1.17.2. Getting the exact same error.

Tried both the copy/paste and replace client_id method as well as the url generated by the script, and I inputted the http://localhost/?code=CIPHER into the program, but I'm still getting the "Invalid code" error. Note, I included it with and without the http://, but running it through a regex simulator with the regex you're doing doesn't make a difference.

Using the docker version from meisnate12/plex-meta-manager on UnRAID.

@meisnate12 tested on 1.17.2-develop3 on unraid via meisnate12/plex-meta-manager:nightly

@linxchaos advise you to use the @chazlarson script
You open a bash to your docker:

apt update
apt install git 
git clone https:/chazlarson/Media-Scripts
cd Media-Scripts/Plex-Meta-Manager/
python pmm_mal_auth.py 
# Copy/paste your Client ID/Secret, then get your redirect URI; it will provide your config to paste for PMM

Happy to test on newest build if you need me~

[linxchaos]

@chazlarson script worked (had to use a different machine to get the script to run, no fault of the script) and it appears that I'm now up and running, but this is still not fixed on PMM proper.

[davidvpe]

To be honest I didn't really want to clone and use yet another script. So out of my laziness I think I found a solution for this.

DISCLAIMER: I am not too sure about this since I still don't understand OAuth2 very well. But here it is

Go to the file ./Kometa/modules/mal.py

Find the line that says

code_verifier = secrets.token_urlsafe(100)[:128]

and replace it for

code_verifier = uni_code_verifier

Like this:

That seems to do the trick. My theory is that the code_verifier used for authentication needs to be the same for token generation.

If you found my answer while searching for your problem and you understand OAuth2 and you are sure this is the way it's supposed to be. Let me know so that I can make a PR and fix this for everybody ;)
