REST: Uri is not absolute / UnknownHostException

Anonymous — Sat, 16 Nov 2024 10:30:10 GMT

Hello,
I try to create a job which do a REST call to the PrimaERP API.
But i can not figure out how to do it properly and now i tried out the following tutorial:
dwetl.com/2015/08/11/trest-use-case-example-use-rest-api-in-talend/

If I use "https:// api.github.com/users/mralexgray/followers" (without space of course) as URL im Getting the following error:

Exception in component tREST_1

If i remove the "https://" and use "api.github.com/users/mralexgray/followers" as URL I am getting the following Error:

Exception in component tREST_1

Slowly I am loosing the hope to get it working, since i've got the same errors on my trys with PrimaERP and already spent many hours trying to get it running.. hope you can help me?
If i use it in my browser it works and response with the xml/jason i want it to give me.
