Local Redirect URI does not accept hyphen/minus

[the_devotional]

I am exploring n8n for AI workflows and I am using "self-hosted-ai-starter-kit" and I want to use the Spotify tool in my workflow. When configuring the credentials I get this Redirect URI:

  http://localhost:5678/rest/oauth2-credential/callback

Since this is a local docker setup it is not so simple to add support for https, so to conform to the restrictions in Spotify regarding http, I can change the host to 127.0.0.1. However, I still cannot use this URI because the hyphen/minus in (the unchangeable) oauth2-credential does not validate as secure in Spotify Developer Dashboard. I can't really see a reason for this character to be disallowed - is this a bug?

Hi @the_devotional 

I have tested your URI after changing localhost with 127.0.0.1, and it worked without a problem.

Could you please copy and past the error message you get, or take a screenshot?

Hello Ximzend!

Thanks for the quick response 🙂

Here are two screenshots from Chrome on MacOS. When the hyphen is present it is not possible to press the Add button, but without everything works as expected. I have also tried the same thing in Safari on MacOS without success.

Hi @the_devotional 

Thank you for the screenshot. I had to create a full new app to get the same error.

I'll escalate it to the Spotify team.
