Workflow does not work well/properly when using `basePath` on Nextjs app

[bhuone-garbu]

I have multiple apps running side by side, and migrating 1 app but incrementally.

App 1 (the first nextjsapp)

• Has all the routes

App 2 (has a base path /v2)

• has workflow apis and routes under the workflows
• App1 rewrites /v2 -> App2 everything works within nextjs

This is on Vercel logs.

Failed to handle /v2/.well-known/workflow/v1/flow Error: Cannot find module './.next/server/pages/clients/.well-known/workflow/v1/flow.js'
Require stack:

  requireStack: [

    '/opt/rust/nodejs.js'
  ]
}

The app side by side is just a thing that exists. But even if I run app2 on it's own locally, I still get:
