Error: Cannot process schema $ref Cannot identify type of schema.

See original GitHub issue

I’m trying to use createGraphQlSchema as described in documentation but getting this error related to local references:

(node:252) UnhandledPromiseRejectionWarning: Error: Cannot process schema '{"$ref":"#/components/schemas/Id_2"}'. Cannot identify type of schema.
    at createDataDef (D:\Projects\graphql\node_modules\openapi-to-graphql\lib\preprocessor.js:436:19)
...

How can i fix this issue? Why it cannot process local references?

Here is parts of my JSON spec where i use references:

// openapi.json
...
    "order_id" : {
              "$ref" : "#/components/schemas/Id_2"
            },
...
"components" : {
    "schemas" : {
...
        "Id_2" : {
            "type" : "string",
            "description" : "Unique order identifier.",
            "example" : "bcc669fa-ef1f-429b-8dea-1bf5ac78f457"
          },
...
    }
}

Thank you for your support. It was just a short part of my OAS. You’re right: after fixing my mistakes it works fine. But i still have schemaValidate exception when i’m trying to process full version of OAS (which is strange because it was generated from working YAML spec using openapi-generator).

I guess we can close this issue. Thank you for your support.

After correcting the references and removing the missing ones, I was able to generate a working GraphQL interface.
