Research direction

Start by tracing the backend PUT request in publisher.Program and the credential payload sent to the Azure API Management backends endpoint. Reproduce the certificate-to-empty-credentials update and verify that publishing succeeds without retaining the old certificate or returning the validation error.

Describe the bug

We want to remove the credentials from a backend configuration while puclishing.
So when overwritting the configuration, we set the array to empty for both certificate and certificateIds.

The configuration is set as follows:

backends:
  - name: "my-backend"
    properties:
      url: "https://example.com"
      credentials:
        certificate: []
        certificateIds: []

However, we still get the error of missing certificate when we try to publish this without the certificate.

Expected behavior

Backend created without any credentials and errors

Actual behavior

We are getting validation error.

crit: Publisher[0]
      System.Net.Http.HttpRequestException: HTTP request to URI https://management.azure.com/subscriptions/***/resourceGroups/***/providers/Microsoft.ApiManagement/service/***/backends/my-backend?api-version=2022-04-01-preview failed with status code 400. Content is '{"error":{"code":"ValidationError","message":"One or more fields contain incorrect values:","details":[{"code":"ValidationError","target":"credentials","message":"Certificate with id 'my-cert' not found."}]}}'.
         at common.HttpPipelineExtensions.Validate(Response response, Uri requestUri)
         at common.HttpPipelineExtensions.PutResource(HttpPipeline pipeline, Uri uri, JsonObject resource, CancellationToken cancellationToken)
         at publisher.Program.<>c__DisplayClass12_0.<<GetPutRestResource>b__0>d.MoveNext()

Reproduction Steps

Create a backend with certificate credentials.

and try to publish a new one without certificate credentials.
