Nodejs_compat in Page Functions

Howdy all, I'm trying to deploy TinaCMS (https://github.com/tinacms/tinacms) self-hosted (https://tina.io/docs/reference/self-hosted/database-adapter/overview/) on Pages using Workers KV. | I set up a functions/graphql.ts to handle a graphql endpoint that imports some nodejs specific libraries from Tina. The deployments failed for it. There was a hint given by the error messages to add nodejs_compat as a compatiblity flag which I proceed to do in the Dashboard for both preview and prodution deployments but this did not seem to change when I retried the deployment. Similarly wrangler pages dev ./out --compatibility-date 21-11-2023 --compatibility-flags nodejs_compat does not seem to work end gives me the same error:

.....

nodejs_compat requires the imports to be prefixed with node: https://developers.cloudflare.com/workers/runtime-apis/nodejs/

Aahhh didn't notice that in the docs. Ok, so i guess monkey patching or rewriting on my end 🙂 Thanks 🙂

I posted a Pull Request to add this information to the error message 😄 https://github.com/cloudflare/workers-sdk/pull/4485
