Generated App Failing – Worker Routes Error

[c-chandrika]

After generating an app using VibeSDK, the generated application is failing when making API requests.

I’m encountering the following error when calling the /api/todos endpoint from the build preview URL.

API Request

curl 'https://8001-b7d564d6-d635-41eb-b74b-cad466fcf17a-cu_cnrotzjglm60o.build-preview.cloudflare.dev/api/todos' \
  -H 'content-type: application/json' \
  --data-raw '{"id":"7e6f3cd8-4954-4fca-867b-732e5683ee91","text":"hi","completed":false,"createdAt":1771659225075}'

Response

{
  "success": false,
  "error": "Worker routes failed to load",
  "detail": "Can not add a route since the matcher is already built."
}

Let me know if any additional logs or configuration details are needed.

Is this something that you tried sharing in the Vibesdk's chat and try to get the agent to debug?
