Error when trying to edit an App: Something went wrong while editing your app.

[Robert52]

Hello devs,

anyone else having this issue ? I have an app where I have some redirect URLS. I wanted to edit them because Spotify changed its policy to have 127.0.0.1 instead of localhost.

See: https://developer.spotify.com/blog/2025-02-12-increasing-the-security-requirements-for-integrating-w...

Anyways, I can't develop locally because I can't edit the app. 

Anyone else having these problems ?

Thanks for your reply, glad im not the only one. So is there a workaround on how you develop locally?

I had the same problem. I already successfully added the correct redirect url a few months ago, but when I wanted to change something yesterday I got the 'something went wrong..' error. In the end I discovered I forgot to remove 1 old http redirect url. After I deleted it, no errors occurred anymore.

Crazy that this is the solution. Well done. 

Indeed I also had some old localhost urls, and that's why i was getting  errors when trying to edit, I only removed 1 and tried to save, but removing all and then saving worked.

Same, but I also had old `http` redirects for my proper public app, and those were also not allowed, so I had to make deeper cuts than just the localhost addresses.
