We're encountering a 404 error when trying to launch the external installation flow for our integration using the URL pattern:
https://vercel.com/integrations/:slug/new
This was previously working as expected just last week. Has there been a change to the expected behaviour or route handling?
For reference, we’re following the documentation here: External Installation Flow
Would appreciate any insights or updates. Thanks!
