Artillery: Foreach not found

[ghost]

Today adding a dictionary to a variable in the yml I got a foreach error.

JS Class

var randomName = faker.name.firstName;
    var randomLastName = faker.name.lastName;
    var addresses = [];

    // noinspection JSAnnotator
    for( var i = 0; i < faker.random.number(5); i++ ){

        var address = new Object();

        address.zipcode = faker.address.zipCode();
        address.city = faker.address.city();
        address.county = faker.address.county();
        address.streetName = faker.address.streetName();
        address.latitude = faker.address.latitude();
        address.long = faker.address.longitude();

        addresses.push(address);
    }

   // console.log(addresses)
     userContext.vars.name = randomName;
     userContext.vars.lastname = randomLastName;
     userContext.vars.address = addresses;
    return done();


yml file
config:
  target: 'http://127.0.0.1:8000'
  http:
      timeout: 10
  phases:
    - duration: 2
      arrivalRate: 2
  processor: "./specs/PersonsFaker.js"

scenarios:
  - name: "Add a person with addresses"
    flow:
      - function: "addPerson"
      - post:
          url: "/person/"
          json:
            firstName: "{{ firstname }}"
            lastName: "{{ lastname }}"
            address: "{{ address }} "
  - log: "Address {{ firstname }}, {{ lastname }}"

This is the output

/node_modules/artillery/lib/commands/run.js:451
    scenario.flow.forEach(function(step) {
                 ^
TypeError: Cannot read property 'forEach' of undefined

I updated with the current main branch and nothing is changing.

Repasted the yml file

Out of curiosity, does the same thing happen if you convert your yaml file to JSON and run that? (You can convert it with npm run artillery convert ./specs/yourFile.yml)

I only ask because the indentation looks a bit off in the yml you shared, and JSON doesn't care about indentation

@ericmacfarland Here is the yml converted to json

            }
          }
        }
      ]
    },
    {

    }
  ]
}

@3lb3njy
I'll take a look, in the mean time, did you receive the same error when you run Artillery with that JSON file?

[ghost]

@ericmacfarland yes I got the same error with the json.

[ghost]

@ericmacfarland the error was in the "Log" tag, it was a wrong indentation.

I got the same Error, testing my echo websocket.

scenarios should be at the top level (same as config)
