Make sure you have configured your project to use modules. You can check Cloudflare docs for more details because it seems you haven't since it asks you to have fetch event listener just like our regular Cloudflare example that uses server.start() instead of exporting the server.

@ardatan Seems like we should update the documentation to be more precise: https://www.graphql-yoga.com/docs/integrations/integration-with-cloudflare-workers

It's your project.

We should add an e2e test similar to https://github.com/dotansimha/graphql-yoga/blob/master/e2e/tests/cf-worker.ts for the cloudflare-modules example.

Could you try to update your wrangler configuration like below and try again? (I just updated the configuration)
https://github.com/dotansimha/graphql-yoga/blob/master/examples/cloudflare-modules/wrangler.toml

Have you published this version using wrangler successfully? I had a similar config yesterday day when I was attempting to get the example working.

[ardatan]

Could you try to deploy the example now? We have just updated the example.

@ardatan can we make sure all the Cloudflare variant examples are end2end tested in order to prevent future regressions?
