Deployment/update error map: map[] does not contain declared merge key: name

When i deploy the first time with k8s deploy everything works fine. But when i deploy the second time i get the following error:

error calculating patch from openapi spec: map: map[] does not contain declared merge key: name

Strange though that when i deploy localy the firsttime with kubectl and update everything works fine. But when k8s has deployed i even can not update with local kubectl i get the same error.

Any ideas what this could be?

This is the deployment yaml:
