Ambiguous URL provided, did you omit the domain in a multi-site setup?

[davidpattaguan-gsquared]

Trying to setup multisite using this repo, are there any existing implementation on how I can do it via this repo?

The question is still relevant.
When adding the second application, I get this error:

[remkoj]

Doing a multi-site isn't yet fully documented. The code assumes the following

• You're deploying an frontend (Vercel Project) per website
• You'll implement a ChannelDefinition (from the @remkoj/optimizely-graph-client) package and provide that to the main catch-all route, so it can filter the routes for the specific website.

The error is showing that the same route exists in more then one application, hence the error. The domain it refers to is normally inferred from the ChannelDefinition.
