Description

The api "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/sites/{name}" supports both LRO/ non-LRO.

the LRO is for function app on container app environment, however, the LRO poller returns error(check code #1) if the result of the polling uri is statusCode 200 + actual function app object. (we only take 200 + empty body as a succeeded polling op: see code #2)
1.

if op.Properties.ProvisioningState == "" && op.Status == "" {
			return nil, fmt.Errorf("expected either `provisioningState` or `status` to be returned from the LRO API but both were empty")
		}

	// Automation@2022-08-08 - Runbooks - returns a 200 OK with no Body
		if result.HttpResponse.StatusCode == http.StatusOK && result.HttpResponse.ContentLength == 0 {
			result.Status = pollers.PollingStatusSucceeded
			return
		}

It makes sense to return the actual provisioned object by the polling uri endpoint, shall we add this scenario as well?

@xiaxyi can you provide the HTTP Requests/Responses involved here?

[xiaxyi]

sure @tombuildsstuff , here you go:
The PUT request to create the function app on container:
https://management.azure.com/subscriptions/85xxx/resourcegroups/xiaxintestrg-linuxOnContainer/providers/Microsoft.Web/sites/xiaxintest-tf-acr130-api?api-version=2023-01-01

      "use32BitWorkerProcess": false
    }
  },
  "tags": null
}

response body of the original URI is the function app object itself

when trying to get the Location in header, request:

https://management.azure.com/subscriptions/85bxxx/resourceGroups/xiaxintestrg-linuxOnContainer/providers/Microsoft.Web/sites/xiaxintest-tf-acr130-api/operationresults/0e10d606-58fe-4842-babd-844a7ac76d6e?api-version=2023-01-01&t=638479026176663501&c=MIIHADCCBeigAwIBAgITHgPpxUXboRMa1MKXpgAAA-nFRTANBgkqhkiG9w0BAQsFADBEMRMwEQYKCZImiZPyLGQBGRYDR0JMMRMwEQYKCZImiZPyLGQBGRYDQU1FMRgwFgYDVQQDEw9BTUUgSW5mcmEgQ0EgMDYwHhcNMjQwMTMxMDEyODE0WhcNMjUwMTI1MDEyODE0WjBAMT4wPAYDVQQDEzVhc3luY29wZXJhdGlvbnNpZ25pbmdjZXJ0aWZpY2F0ZS5tYW5hZ2VtZW50LmF6dXJlLmNvbTCCASIwDQYJKoZIhvcNAQEBBQADggEPADCCAQoCggEBALigL_YnYGZkISCK9BFT_dzpf963u9bRlY_IhMLl8TQ-....

Before function app is provisioned the response is 202+empty body, after the function app is provisioned, response is 200 + actual function app object:
