Describe the bug

I am using graphql-codegen with typescript and it works fine, but on provided query, codegen throws
Error 0: Unknown type "UUID". Did you mean "ID"?

I cannot replace "UUID" with "ID" as its used in company's schema and cannot be changed (only names there were changed)

const CREATE_TOKEN = /* GraphQL */ `
  mutation GenerateToken($uuid: UUID!) {
    generateToken(uuid: $uuid) {
      token
    }
  }
`;

export default CREATE_TOKEN;

Steps to Reproduce the Bug or Issue

Expected behavior

I expected this query to have generated types, not throwing an error

well this would work. Can you ensure that the Schema that is being served has the UUID scalar declared in it? It would be great if you can share a minimal reproduction. You can either use StackBlitz, CodeSandbox or a public GitHub repo.

i get Error 5: Unknown type "uuid". when i have used hasura

const UPDATE_USER_MUTATION = gql`
  mutation ($id: uuid!, $displayName: String!, $metadata: jsonb) {
    updateUser(pk_columns: { id: $id }, _set: { displayName: $displayName, metadata: $metadata }) {
      id
      displayName
      metadata
    }
  }
`

basically i am using hasura which has the type uuid and it is complaining that i have uuid as part of my queries

It doesn't matter if you use Hasura or something else. If your schemas doesn't have scalar uuid, this won't work.

[eleijonmarck]

is there a way to add it "manually", as my schema is generated from hasura and will be overwritten with each change on the schema

[ardatan]

You can provide multiple sources for the schema;

Config:

schema:
   - https://WHATEVER-URL.com
   - ./my-extra-typedefs.graphql

In that file;

scalar uuid
