Karate 1.0.1 NullPointerException when sending a number in a PUT request

Going from karate 0.9.5 to 1.0.1 I found that sending a PUT request with a number returns a java.lang.NullPointerException.

e.g.

In v0.9.5 this was working:

Given path 'v1', 'users'
And request 7
When method PUT
Then status 400

Now it returns a NullPointerException:

To reproduce :

  @PutTest
  Scenario: Put Test
    Given url  'https://www.google.com/'
    And request 7
    When method PUT
    Then status 400
