Numbers can not be appended as http request to urls

[matteo-cristino]

I was trying to append a number as a http parameters at a url

Scenario 'http': compose url

Given I have a 'number' named 'id'

When I create the url from 'redirect'
When I append the percent encoding of 'id' as http request to 'url'

Then print the 'url'

with data

{
	"id": 6,
	"redirect": "https://example.org"
}

but this is not working
