--cucumberjson-expanded does not work for pytest.mark.parametrize

Step name does not contain argument value in scenario outline in Cucumber JSON report when I use @pytest.mark.parametrize decorator.

Version: python==3.7.3 pytest==5.1.2 pytest-bdd==3.2.1

# -- FILE: scenario_outline.feature
Scenario Outline: Outlined given, when, thens
    Given there are <start> cucumbers
    When I eat <eat> cucumbers
    Then I should have <left> cucumbers

# -- FILE: scenario_outline_test.py
import pytest
from pytest_bdd import given, when, then, scenario


@pytest.mark.parametrize(['start', 'eat', 'left'],
                         [(15, 7, 8),
                          (15, 5., 10)])
@scenario(
    'scenario_outline.feature',
    'Outlined given, when, thens',
    example_converters=dict(start=int, eat=int, left=int)
)
def test_outlined(start, eat, left):
    pass


@given('there are <start> cucumbers')
def start_cucumbers(start):
    return dict(start=start)


@when('I eat <eat> cucumbers')
def eat_cucumbers(start_cucumbers, eat):
    start_cucumbers['eat'] = eat


@then('I should have <left> cucumbers')
def should_have_left_cucumbers(start_cucumbers, start, eat, left):
    assert start - eat == left
    assert start_cucumbers['start'] == start
    assert start_cucumbers['eat'] == eat

I run the test with following options:

python -m pytest scenario_outline_test.py -s -vvv --cucumberjson=cucumber.json --cucumberjson-expanded

Here is my output from cucumber.json:

"steps": [
          {
            "keyword": "Given",
            "name": "there are <start> cucumbers",
            "line": 2,
            "match": {
              "location": ""
            },
            "result": {
              "status": "passed",
              "duration": 996589
            }
          },

It works fine when I use Example in the feature file.

Hello, i have an issue and i think it is the same as you. I try to generate a cucumberjson file by using : py.test test_feature_sample.py --cucumberjson=cucumberjson.json --cucumberjson-expanded

I get the following error:

pytest_bdd\cucumber_json.py", line 111, in _format_name name = name.replace('<{}>'.format(param), value) TypeError: replace() argument 2 must be str, not

If i do not use " --cucumberjson-expanded" it works like a charm. I think it is cause because i have a scenario defined as : @scenario('....','....', example_converters=dict(stringvalue=str, intvalue=int, concat_value=str))

and then the following call fails (file cucumberjson.py):

 def _format_name(self, name, keys, values):
        for param, value in zip(keys, values):
            name = name.replace('<{}>'.format(param), value)
        return name

It fails because value is expected to be a string while it has been converted by example_converters property into an int. I am able to resolve my problem simply by updating the code to:

def _format_name(self, name, keys, values):
        for param, value in zip(keys, values):
            name = name.replace('<{}>'.format(param),str(value))
        return name
