I think you need to set the query parameters (i.e. the "Parametres de la requite"). They are missing in your job, but present in the Talend documentation for tRESTClient.

Hope this helps,

I replaced the { and } in the parameters fields and it seems to be better.

Now I have other exception. I think the special characters in my URI have been coded :

? replaced by %3F

{ replaced by %5C%7B

} replaced by %5C%7D

That is part of URL encoding; it is standard practice, and shouldn't cause an error:

You're getting an "unknown host" exception, so the component can't resolve your hostname. Try pinging the hostname to make sure your workstation can reach it; you might also try using the IP address instead of the hostname and see if that fixes the error.

Hi,

I found a way to solve my differents issues :

In the parameters settings, i replace the { by %7B and } by %7d
Delete the "?" of my URI in the relativ path
I used the proxy settings of my company

Hope it will be helpfull for the community and thks a lot for your help !
