Failed to complete OAuth but the app is still installed

[tnet1399]

I am developing an app and facing this strange issue: when installing the app to the development store, I get this error on the terminal: 

"[shopify-app/ERROR] Failed to complete OAuth with error: Error: GraphQL query returned errors"

It seems to be an issue during the OAuth process, however, my app is still installed and I can use my app like nothing happened. Am I missing anything? If you need something from my code, I'd be please to share. Thanks in advance.

Hey @tnet1399 

The error message you mentioned, "[shopify-app/ERROR] Failed to complete OAuth with error: Error: GraphQL query returned errors," indicates that there was an issue during the OAuth process when installing your app to the development store. Although the error occurred, if your app is still installed and functioning correctly, it could be a transient issue or something to investigate further.

Here are a few steps you can take to troubleshoot the issue:

1. Verify your OAuth implementation: Double-check your OAuth implementation to ensure that you are correctly handling the authentication flow. Review the Shopify API documentation and make sure you have followed the necessary steps for OAuth authentication.

2. Check your GraphQL queries: The error message mentions that a GraphQL query returned errors. Review the GraphQL queries in your app and ensure they are properly structured and comply with the Shopify API requirements. Pay attention to any specific error messages or error codes that may provide more information about the issue.

3. Test in different environments: Try installing your app on different development stores to see if the issue persists. It's possible that the error is specific to a particular environment or configuration.

4. Review app permissions: Ensure that your app has the necessary permissions to access the required data and perform the desired actions. Check your app's API permissions and verify that they align with the functionality you are implementing.

5. Check app logs and error handling: Review your app's logs and error handling mechanisms to see if any additional information is available about the specific error. This could help you pinpoint the issue and implement appropriate error-handling strategies.
   
   

If you are unable to identify the cause of the error or resolve it through troubleshooting, it may be helpful to consult Shopify's documentation, reach out to Shopify's developer support, or provide specific code snippets for further analysis.

most of the solutions shouldn't really apply to the standard app template developers download to kickoff boilerplates on test environments.
