I'm beginner of Talend studio and don't know how to use all of components correctly.
Here got one issue if I passed a lot string data cross over the tRESTClient, but API received with null value.
So, I checked in input schema of string under tRESTClient component, it was allow 4048 characters only.
Is it able to increase more?
Can see detail in attached screen captured.
Have you tried to use talend ESB component to build the restful webservice to see if you can pass a very long string parameter?
Is the restful webservice hosted with Talend component or other third party provider?
