Generation of Shopify GraphQL schema fails

[mairas]

Describe the bug

I have downloaded the latest GraphQL schema of our Shopify store with the following commands:

npm install -g get-graphql-schema
get-graphql-schema -h 'X-Shopify-Access-Token=REDACTED' https://hat-labs.myshopify.com/admin/api/2024-04/graphql.json > shopify_schema_2024-04.graphql

The downloaded schema is attached below.

I am attempting to use the following command to generate data models for it:

datamodel-codegen --output shopify_gql_schema.py --input shopify_schema_2024-04.graphql --input-file-type graphql --target-python-version 3.11

This results in the following stack trace and error:

To Reproduce

Example schema:

Renamed to .txt to allow uploading: shopify_schema_2024-04.txt

Used commandline:

$ datamodel-codegen --output shopify_gql_schema.py --input shopify_schema_2024-04.graphql --input-file-type graphql --target-python-version 3.11

Expected behavior

I assumed I'd get a Pydantic schema definition in the output file. This is my first time trying to use datamode-codegen, so my expectations were quite vague. :-)

Version:

• OS: MacOS Sonoma 14.2.1
• Python version: 3.12.2 (Installed using Conda)
• datamodel-code-generator version: 0.25.5
