proxy timeout error

[doberkofler]

I'm using the koa-proxies module as part of my web-test-runner infrastructure for unit tests to forward calls to my app backend.
This does generally work as expected but when the backend does not respond within 2 seconds the proxy responds with:

2024-11-12T20:23:49.978Z - POST /BACKEND/TST_UNITTEST_UiButton.click proxy to -> http://127.0.0.1:7777/ords/lj_unittest/TST_UNITTEST_UiButton.click
Error while handling server request.
Error: Http response closed while proxying /BACKEND/TST_UNITTEST_UiButton.click
    at ServerResponse.<anonymous> (/*/node_modules/koa-proxies/index.js:99:16)

It seems to some kind of timeout error in the proxy itself but I cannot seem how to increase it?

My proxy configuration looks like this:

proxy('/BACKEND', {
	target: getBaseURL(),
	changeOrigin: true,
	rewrite: (p) => p.replace(/^\/BACKEND/, ''),
	logs: true,
})
