Node start failed in VMQ_MZbench example

[Niclas Zellerhoff]

I am trying to run the VMQ_MZbench sample test, i.e. with the following code (only the MQTT broker has been customized):

#!benchDL


#######
# Scenario:
# A single subscriber reading from "prefix/clients/#" topic filter
# 1k publisher publishing to exclusive topic "prefix/clients/{client_id}"
# Overall msg rate: 1k msg/s
# Message size: 150 random bytes
# Running time: 5 min
#######

make_install(git = "https://github.com/vernemq/vmq_mzbench.git",
             branch = "master")

pool(size = 1,
     worker_type = mqtt_worker):

            connect([t(host, "broker.mqttdashboard.com"),
                    t(port,1883),
                    t(client,"subscriber1"),
                    t(clean_session,true),
                    t(keepalive_interval,60),
                    t(proto_version,4), t(reconnect_timeout,4)
                    ])

            wait(1 sec)
            subscribe("prefix/clients/#", 0)


pool(size = 1000,
     worker_type = mqtt_worker,
     worker_start = poisson(1000 rps)):

            connect([t(host, "broker.mqttdashboard.com"),
                    t(port,1883),
                    t(client,fixed_client_id("pool1", worker_id())),
                    t(clean_session,true),
                    t(keepalive_interval,60),
                    t(proto_version,4), t(reconnect_timeout,4)
                    ])

            set_signal(connect1, 1)
            wait_signal(connect1, 1000)
            wait(4 sec)
            loop(time = 5 min, rate = 1 rps):
                publish_to_self("prefix/clients/", random_binary(150), 0)
            disconnect()

However, I get the following errors:

17:47:19.109 [error] [ API ] <0.502.0> [ REMOTE EXEC ] Command execution failed: Cmd: bash -c -l "export PATH='/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'; cd /tmp/mz/bench-1-1626198400 && ~/.local/share/mzbench/bin/mzbench start " Exit code: 1 Output: Node start failed

I am using the latest Dockerfile, built directly from the master branch. The simple test example (when creating a new benchmark) works without any problems.

Just tested it with this Dockerfile - works perfectly, so it seems to be a Docker-related problem.
