DB Intern / DB internal

Hello dear NIFI Team,

We are using Apache NIFI in our Azure Cloud Infrastructure. As of recently we 
cannot fetch parameters via the parameter provider anymore (updated from 1.25 
to 1.26).
The setup is the following:

  1.  Getting access to the Azure resources via 
StandardAzureCredentialsControllerService 1.26.0 (via managed Identity)
     *   The validation checks out (but unfortunately it also does when the 
given Client ID was wrong on purpose)
  2.  Fetching the Parametes via AzureKeyVaultSecretsParameterProvider 1.26.0 
(via StandardAzureCredentialsControllerService 1.26.0)
     *   The validation throws an error: service not available 503

I've run a python script on the VM (which is running our NIFI instance) and 
with that script I could successfully fetch a parameter from the KeyVault via 
the Managed Identity. The infrastructure seems fine.
Therefore I would like to ask if you can proof, If the required components are 
working since the last update to 1.26.0?

Thank you very much and greetings from Germany,
