Subject: shopify app dev failing with 500 error - GCS authentication issue

Hey everyone,

Is anyone else experiencing issues with shopify app dev right now? I’m getting a 500 error across all my extensions that was working perfectly fine just minutes ago.

Error:

unexpected status code: status=500 body={"error_message":"failed to get module from GCS: cannot create the authentication headers Request to fetch the token failed. Subsequent calls with this credential will also fail. and future attempts will not succeed","error_type":"StorageError"}

This is happening for all my extensions (discount functions, validations, transformations, etc.) when trying to run the dev server or update app preview.

What I’ve tried:

  • The command was working fine earlier today

  • No changes to my environment or credentials

  • Issue started suddenly

Questions:

  • Is this a known Shopify/GCS infrastructure issue?

  • Anyone else experiencing this at the moment?

  • Any suggested troubleshooting steps?

Any insights would be appreciated!

This has been solved, disregard!
