scenario with multipart field

[yunjoopark]

After upgrading to 1.0.1, I faced this issue.

In the following feature, multipart field is a json .
I passed it converted to a string to build a request successfully in multiPartInternal()

Scenario: karate test
    * url endpoint
    * def abc =
    """
    {
      a: 'b'
      b: {
        c: 'd'
      }
    }
    """

    Given path '/api/path'
    And headers required_headers
    And multipart file mediaFile = { read: 'image.png', filename: 'image.png', contentType: 'image/png'}
    And multipart field abc = JSON.stringfy(abc)
    When method post
    Then status 200
    And match response.status contains 'ok'

The feature failed with the following output.

{"message":"Content type 'text/plain;charset=UTF-8' not supported"}

logs:

content-disposition: form-data; name="abc"; filename=""
content-type: text/plain; charset=UTF-8
content-length: 27
Completed: true
IsInMemory: true

try this please:

And multipart file abc = { value: '#(abc)' }
