Okay, I was stupid enough to include the curly brackets in the httpClient request. Removed the curly brackets, and everything worked. BUT. the curl command line command works WITH the curly brackets. I.e. the behaviour is definitely different.
What are you trying to achieve here, exactly? This looks like you’re trying to get a remote-config content without using the SDK. Is there something wrong with the SDK?
It will handle the web request for you, all you have to do is init the services…
What you are trying to do is possible but not really necessary, I strongly recommend you use the SDK.
It’s also hard to tell what the curl command was, you could just share the real URL (project ID and env ID), since not much can be done without the token anyway.
