Troubles with local installation: can't get through github app auth

[RobErskine]

Hi there,

I am trying to install Outstatic in my new Next.js 15 project utilizing with-supabase.

I have isolated my codebase into a (cms) and (main-app) route groups to isolate functionality.

I followed all of the instructions in the documentation twice over now and I'm not sure what I'm doing wrong.

I created a Github App and am trying to use that for auth. I get redirected to github, auth with my app, then get redirected to my app. However I get redirected back to the original /outstatic page. When refreshing, I can see my auth cookies get set for a split second before being removed. I also get a few console CORS errors, but the instructions doesn't say anything about those.

Here is a video recording of what I am experiencing: https://screen.studio/share/ZtPAdUhK

I've created a snapshot of my repo where this issue is happening here: https://github.com/RobErskine/bard/tree/outstatic

Any help would be greatly appreciated. I'd love to help update any docs or anything if we're able to get this resolved.

Looking forward to using Outstatic soon!

I just tried on a completely fresh Next.js 15 install and see the same thing happening, so I am not sure if it is how I configured my Github App or something else?

Here is the fresh repo: https://github.com/RobErskine/outstatic

Hey @RobErskine ,

Thank you for reporting this issue. Next.js 15 brought a bunch of bugs.
I'm working on fixing this. I'll review your issue sometime tomorrow.
Cheers.

I'm having the same issue:

• Can't login into Outstatic after Next.js 15.1.4 and React 19 upgrade #274

In case it's helpful, I've asked ChatGPT Plus about the issue. Curious why this issue only manifested in Next.js 15.x.

Same problem here.
I tried GitHub OAuth and GitHub Apps. Both result in the same cors error:

Did also try to bypass CORS in dev installing a chrome plugin which adds allow origin *. However still no luck.

Node: v20
Next: 15.1.6

Hey folks, I apologize for this.
Can you try installing outstatic 1.5.0-canary.2?

There's a short explanation here: https://github.com/avitorio/outstatic/blob/canary/apps/docs/outstatic/content/docs/upgrading-to-v1.5.mdx

Let me know if this works.
