onConnectionError is not called for workers

Hello!

We are facing some errors on the workers side, but the onConnectionError() never gets called. For example:

15:56:47.739 | zeebe |  [http] INFO: Grpc Stream Error: 1 CANCELLED: Received http2 header with status: 502
15:56:52.541 | zeebe |  [eval] INFO: The gateway returned HTTP Error 503 (Bad Gateway). This can be a transient failure while a Kubernetes node in Camunda Cloud is being pre-empted.
07:51:16.276 | zeebe |  [http] INFO: Stalled on Grpc Error
07:51:16.281 | zeebe |  [http] INFO: Grpc Stream Error: 14 UNAVAILABLE: TCP Read failed
09:49:54.840 | zeebe |  [eval] INFO: Stalled on Grpc Error
09:49:54.840 | zeebe |  [eval] INFO: Grpc Stream Error: 14 UNAVAILABLE: failed to connect to all addresses
10:05:03.134 | zeebe |  [http] INFO: Stalled on Grpc Error
10:05:03.134 | zeebe |  [http] INFO: Grpc Stream Error: 14 UNAVAILABLE: GOAWAY received

Also when we create a workflow instance the workers continue to work despite those errors, so I suppose these errors shouldn’t affect us right? We use latest version of library (0.24).

  worker.on('ready', () => {
    console.log('worker is ready!');
  });

is working for me

The onReady() doesn’t get called as well if this helps.
