Playnite 8 Playstation library support fails to authenticate

[adrianluff]

Playnite 8 fails to import Playstation library games with the error "Object reference not set to an instance of an object." immediately after authenticating from Settings -> Libraries -> PlayStation or "User is not authenticated" after the first attempt.

This issue may be related to two factor authentication being enabled on the PSN account.

Playnite log reports:

I can't reproduce it myself, but I'll prepare debug build of PSN plugin to help me debug this.

[adrianluff]

I did try generating a device code (app password) from the Sony account page. That password was not accepted via the web form though.

[JosefNemec]

I'm pretty sure that 2FA is not an issue here, since the error is not related to the authentication process. At least for me it works with 2FA just fine.

Please use this debug build of PSN plugin, reproduce the issue again and generate new diag. package. Thank you (the files go into %localappdata%\playnite\extensions\PSNLibrary\ directory).

[adrianluff]

It didn't dawn on me before but I bet the issue is my PSN library is larger than expected. My download list shows 6,551 items.

[JosefNemec]

Yeah, the size of the library may cause issues. I got similar report from user on Discord and it seems I will have to adjust some timeouts. Thanks for new diags.

[JosefNemec]

Are you sure you've overwritten plugin files correctly? I don't see new debug information in logs and trace lines are from old code as well.

[adrianluff]

Ah, nope. I added it to %appdata% not %localappdata%. Fixed.

Log had hundreds of lines like the first line here for different content, then:

[JosefNemec]

New version of PSN plugin. Let me know if it works with this one.

[JosefNemec]

Btw, Sony changed something on their side yesterday/today and the Plugin is now completely broken...

[adrianluff]

Sony made a big change to trophy levels yesterday. Not sure how that affected the APIs you use.

[JosefNemec]

New version is available, authentication should work now.

You will also need to replace these files in Playnite's install directory, because I had to make changes to the SDK. Make backup of the originals, because some things like IGDB integration will not work with these! They are only for testing of this PSN issue.

[adrianluff]

Crashes on startup with those files. I made sure to put them in %localappdata% this time! Restoring the previous Playnite DLL and SDK DLL files allowed it to launch again.

Here's the log...

Hmm, I guess you would have to have build from devel. I've had another person test this and it works for them (they had similar issue as you). I'll release it with 8.1 update. If it still doesn't work then, let me know.

Will do.

Confirmed fixed in 8.1
