Hello Alex,Could you precise your environment? I've tested with the Simple connector, and I get back 404 status which is not so bad but may be improved.
Best regards, Thierry Boileau
If you do a GET on a URI that is too big (4k by default), the response status will be 'null (-1)'. A quick look at the standard HTTP codes says that it should be 'Request URI too long (414)'. Something to incorporate.
