Getting GraphQLError: Syntax Error: Cannot parse the unexpected character #41

Closed netpoe closed 4 years ago

netpoe commented 4 years ago

When running graphql-schema-typescript generate-ts ./src/datamodel/testSchema.graphql --output ./src/datamodel/testSchema.d.ts from my package.json script: 

"generate:schema": "graphql-schema-typescript generate-ts ./src/datamodel/testSchema.graphql --output ./src/datamodel/testSchema.d.ts"

I get the following error: 

$ graphql-schema-typescript generate-ts ./src/datamodel/testSchema.graphql --output ./src/datamodel/testSchema.d.ts
Message:  null

I've tried with escaping double quotes, single quotes, etc. I've also tried to use the testSchema.graphql from the __tests__ to no avail.

Seems like a parse issue with the directory paths?

Has the same issue after adding union FullWidget = Widget | JSON

@QuestionAndAnswer in my case, I ended up using: https://www.npmjs.com/package/@graphql-codegen/typescript-resolvers instead of this.
