Vercel Deployer always leads to Empty Builds

/swagger-ui
always shows a 404 error, as if no agents / workflows exist when it deploys to Vercel.

However, normal .mastra/output builds wthout using
new VercelDeployer()
shows the playground and swagger-ui correctly as it should.

EDIT: Now for some reason, even non-vercel-deployer builds come empty with no api routes and agents and workflows.
