System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found) + API Management DevOps Resource Kit

Question

Hi Community

I'm using the API Management DevOps Resource Kit (https://github.com/Azure/azure-api-management-devops-resource-kit) to extract the ARM Templates from a tenant. The toolkit worked well (and still working) with at least 5 API instances, but is failing to extract one particular API instance. Here's the error I'm seeing:

Started generation of ApiManagement service template...

[12:46:20 ERR] Error occured: Response status code does not indicate success: 404 (Not Found).

System.Net.Http.HttpRequestException: Response status code does not indicate success: 404 (Not Found).

Any pointers to troubleshoot the issue will be greatly appreciated.

Thanks for posting your question in the Microsoft Q&A forum.

This could happen due to a few reasons:

1. Ensure the account used for extraction has necessary permissions, like the "Reader" role on the API Management service.
2. Check for network issues or firewall rules that could hinder access to the API Management service.
3. Verify the API Management service is healthy and not undergoing changes like updates or deletion.
4. Confirm the provided resource ID or name matches the intended service for extraction.

Some troubleshooting steps you can try:

1. Ensure the service principal or user account has the "Reader" role on the API Management service resource.
2. Consider using a different authentication method if encountering issues.
3. Network Connectivity: Test the extractor from a different network or machine to troubleshoot connectivity problems.
4. Verify the API Management service status to ensure it's not undergoing updates or deletion.
5. Double-check the provided resource ID or name against the actual service in Azure portal or CLI.
