Since this issue has sat for so long, we have no record of that run. Adding another intermittent failure to this issue: https://github.com/hyperledger/firefly-fabconnect/actions/runs/6253967362/attempts/1

Running the same job again resulted in a successful run: https://github.com/hyperledger/firefly-fabconnect/actions/runs/6253967362/attempts/2
