Spotify for Developer Flickering After Making Second Application

My Question or Issue

Let me start by sharing that I need to make this message logged out of my account, because even logged into my account, it won't let me access this page.

On the Spotify for Developers page, I made a second application with the same ''http://127.0.0.1:5000/callback''. I was planning on using this application as a tutorial to share the community how to use this other application called ''TTS Voice Wizard.'' To show this, I had to save the second application (so I already had one that was working just fine!), to then show where to find the ''Client ID''.

However, when I tried to press save on the second application, it started going HAM. My entire Spotify for Developer dashboard page started flickering. It could not load anything and honestly, it just looked like it tried to load a page that was not able to be loaded. I pressed ''F12'' and got some information out of there, it just showed me a bunch of Java Scripts errors and that it was unable to load the page. While before I made the second application, it was still possible. Within a minute there was over 1000 errors.

I tried the following:
- Logging in and out, using the same browser.
- Incognito on the same computer.
- My phone and login to the same account on the site.
- ANOTHER computer logged into the same account.

It happened in all these cases and I am honestly done trying new things.

After all of this, I tried contacting support and I got to talk to someone other than the AI. They told me to make a post here. When I logged into my account on THIS site, it also refused to load the ''message'' page, while it did load everything else on this page. So that is why this message is private, I would have liked to have seen that differently obviously.

So in short.. The issue reproduces across multiple browsers, operating systems, devices, and networks. It began immediately after creating a second Developer application. The Developer Dashboard now crashes with a JavaScript exception (TypeError: Cannot read properties of undefined (reading 'charAt')) and continuously reloads. I have no further understanding of coding, computers or anything so I hope this is helpful enough.

All I want now, is someone to just take a quick look at my Developer page and delete both of my applications, so I can redo it. Obviously I am anonymous right now since I can't send it through my own account, but if there is anyone that can reach out to me, that would be delightful.

Okay now it does want to log me in. I am utterly confused. Also here is a video on what I am seeing.

I am having the same issue. When looking at the console log of the dashboard on my browser, I see hundreds of errors per minute. The page is trying to load the script https://cdn.cookielaw.org/scripttemplates/otSDKStub.js but the DNS for cdn.cookielaw.org does not exist. In addition, I am seeing hunderds of http 401 and 429 errors and javascript errors of attempting to execute a charAt on a property that doesn't exist (looks like the name property of a form field that hasn't been rendered or loaded yet).

This happened after doing some cleanup in my dashboard. I removed all my existing apps and added a single new app. I also noticed that this started happening around the same exact time that the Spotify service was having issues.

The developer dashboard is now loading for me again. My guess is that they were having trouble with it today. You should try logging in again and checking.

If you have any part of the project in a ZIP file, could you share it? It's hard to explain here—maybe there's a function you've set up incorrectly.

Ah Thank you so so much! I was worried this would go on forever. Sometimes it is just reassuring to see someone else have the same issue, knowing I am not the only one. I am glad it is fixed, it did for me too!

I just opened a thread about this because today my dashboard started giving me infinite errors and is stuck in a loading loop. I really don't know how to fix it!
