same issue here. though the pod is getting created, and I am able to update the pod with an additional volume as well. each time it throws the error, but the pod seems to getting created and updated correctly.

Some additional info that might help. This seems to be caused by the ServiceAccount token auto mount under volumes. Adding an additional element to the list of volumes, confusing the provider. Setting automountServiceAccountToken: false works happily without any errors.
