Vercel Postgress Error Codes

This section focuses on errors that can happen while using the Vercel Postgres SDK to interact with your Vercel Postgres store.
ReplyError: invalid_connection_string

Your postgres client was not able to connect to your Postgres store. This error happens if you provided the wrong type of connection string to a connection method.

For example, you passed a non pooling postgres URL to the createPool method which expects a postgres URL that includes pooling.

  • Check that your connection string does not have a typo, or that it is associated with the correct type of connection (direct or pooled)
ReplyError: missing_connection_string

  • Check that you used the correct parameter name for the connection string.
