For info, you are almost certainly not actually using that location{} block.

$variables are not expanded in "location" directives.

It may well be that your :8041 backend is working fine; but the error
message you showed was about your :8042 backend; and as far as nginx
was concerned:

upstream sent invalid chunked response

How do you know?

Can you use something like "tcpdump" to show the traffic from the backend
when nginx reports a problem, and when things work correctly?

Perhaps that will show what the difference is.

In the logs you provided, the request was "GET /bsg/scrips"; does nginx
always report a problem when you make that request?

Good luck with it,
