Describe the bug

Unable to properly generate types, returns JSON instead.

Maybe there is a problem with the YAML file but it seems to validate OK in online validators.

To Reproduce
Steps to reproduce the behavior:

I have setup a codesandbox here:
https://codesandbox.io/s/staging-lake-ervh5v?file=/swagger.yaml

Expected behavior

Graphql-mesh should generate the proper type.

Environment:

• Packages

  "@graphql-mesh/cli": "0.70.3",
  "@graphql-mesh/openapi": "0.25.6",
  "@graphql-mesh/transform-resolvers-composition": "0.12.53",
  "graphql": "16.0.1",
  "graphql-fields": "2.0.3"

Many thanks for your time and help.

If the type is not a certain object type, it puts an empty JSON type. Please make sure you have a correct schema type in your OpenAPI schema.

Not sure to understand... could you give an example of something wrong in the yaml file please?

Hello, I have the exact same issue, as @gablabelle described.
@ardatan can you give an example of what you are suggesting based on the codesandbox that was given?
Thank you.

Currently we are rewriting the OpenAPI handler and releasing it as newOpenapi handler which is named as @graphql-mesh/new-openapi under NPM;
You can see the configuration schema here;
https://github.com/Urigo/graphql-mesh/blob/master/packages/handlers/new-openapi/yaml-config.graphql

We cover more cases than the old open api handler. I did more improvements and fixes based on Toto's schema you provided;
#4221

You can test it using canary versions commented in the PR until it gets released and we'd appreciate if you give us a feedback in the meanwhile :) If you have any more issues, feel free to create a new issue with a reproduciton on CodeSandbox or StackBlitz or a failing test PR :)

Thank you very much for all those information.
