Deadlock when using @passobj

[dkiese1]

When executing the following

using Distributed, ParallelDataTransfer
addprocs(4)

function sendrcv(a)
           b = a
           sendto(workers(), b = b)
           for worker in workers()
               @show @getfrom worker b 
           end
           b = rand() 
           @passobj 1 workers() b
           for worker in workers()
               @show @getfrom worker b 
           end
      end

sendrcv(1.0) 

I encounter a Deadlock after @passobj is used. Julia version is 1.4, OS is Mac.
