I suddenly started to get a 403 error before bulk inserting products.
I bulk insert multiple products and I write necessary params in a jsonl file and reserve a staged upload url by this graphql query.
This worked before, but I suddenly started to get 403 errors. When I connect to a different test shop, my code works, so I wonder why I get this error for this specific store
Generally for store specific access denied errors a key troubleshooting step is to query the app’s available access scopes and to ensure the app is still installed and has permission appropriate to the operation being attempted. Here’s some documentation about that: [appInstallation in GraphQL - Shopify Dev Docs]
If the error persists only for a specific store you may want to open a support request through your partner account at [Shopify Partner Support] including more specific details about a recent test and the store it was performed on so it can be investigated further.
