Hi Chesnay

Adding on to this point you made - " the rpc address is still *required *due
to some technical implementations; it may be that you can set this to some
arbitrary value however."

For job submission to happen successfully we should give specific rpc
address and not any arbitrary value. If any arbitrary value is given the
job submission fails with the following error -
