I can add that this problem is augmented in a dask_gateway system where the task just fails.

With apply_ufunc I never received an error but in similar context I obtained something very similar to https://github.com/dask/dask-gateway/issues/404.

My interpretation is that the Future is resolved at the worker (or in case of apply_ufunc a thread of this worker) and embeds a reference to the Client object. This last however uses a gateway connection that is not understood by the worker as generally is the scheduler dealing with those
