HTTP headers are attempted to be set after the response is send

[d0ctr]

Have received such error, I suppose some of the grammy's code is the reason.

node:_http_outgoing:696

throw new ERR_HTTP_HEADERS_SENT('set');

^

That is possible. Do you use the "express" adapter? Can you share some code that lets us reproduce the problem?
