What happened?

Hi,

I cannot get the REST client query parameters to work:

• the "Parameter Field" dropdown is empty, but when you use the "Get Fields" button, you get all fields in both "Parameter Field" as well as "Parameter Name", while the latter field doesn't have a dropdown
• I've tried several ways, but none have added a query parameter to the URL, nor given an error message
• I've had to look up matrix parameters in Google to get an idea about the difference between "Parameters" and "Matrix Parameters": a short example showing the difference would be helpfull

Can you please improve documentation: what should one do in order to use Parameters?

Currently I'm just building my URLs and doing URL encoding in a Formula transformation: but this adds extra complexity that should be handled by the REST client transform.

Agreed that the documentation can be better.
You can find a bunch of examples in https://github.com/apache/hop/tree/main/integration-tests/http
