Error running benchmark on version 0.4.0 | Ethereum

[fbalwy]

Hello, I am trying to run the simple scenario example on the Ethereum, but facing the following errors

2020.10.18-04:27:11.799 error [caliper] [round-orchestrator]    Failed round 1 (open): Error: Error: Module "/Users/fbalwy/Desktop/caliper-benchmarks-0.4.0 3/benchmarks/scenario/simple/open.js" could not be loaded: TypeError: Class extends value #<Object> is not a constructor or null

I have only changed the networkconfig.json to be able to run the benchmark on local Ethereum network

I've now been able to run the simple scenario using caliper 0.4.2 with no issues with the workload files, this could have been a problem with 0.4.0. Please try again with caliper 0.4.2 and see if the problem persists. Details on how I made it run are described in #168
