Uncaught exception in the SynchronizationContext

Hey, when uploading operations I sometime get this error:
UNKNOWN: Uncaught exception in the SynchronizationContext
Seems like a problem with the SynchronizationContext that the GRPC uses.
Please let me know if you encountered this issue before and know what to do with is,
Thanks!
