Http Post 2.0 gives is not a valid URI error

Hello,

Im trying to method Post json request but Im gettng this error:

exception=java.lang.IllegalArgumentException: the value 'xxx' is not a valid URI.

So I guessed that you have to encode the URL. So I'm using the URL Encoder operation.

My question is. What part of the URL do I encode?

The URL looks like this: https://<Base URL>:443/<Resouce>?<Parameters>

If I encode the whole thing I get this error. If I encode only <Resouce> until the "?" I get the same error. If I encode <resouce> and <Parameters> I get the same error.

Inputs of Http Client Post look like this:

Please help me fix this. Thank you,

Filip
