Shopify Apps

Topic summary

A developer encounters a 403 error when making OAuth access token requests through Shopify’s API, specifically from @shopify/shopify-api/node_modules/node-fetch/lib.

Environment:

  • Using @shopify/shopify-api v10.0.0 with App Bridge v3.7.7/v4.1.3 and Polaris v13.4.0
  • Node v20.14.0 on Ubuntu
  • Debug logging enabled

Symptoms:

  • React app with App Bridge fails to load after a few days of dev store installation
  • Error occurs during backend authentication/API calls
  • Stack trace points to TLS socket errors and client request failures

Current Status:

  • Issue appears intermittent (app stops loading after initial successful installation)
  • Developer has checked repository issues without finding similar cases
  • Root cause of 403 response and connection timeout remains unresolved

The post seeks clarification on whether this is expected behavior or a configuration issue, with request for more detailed error information.
