pawarJayesh8511 opened a new issue #4924:
URL: https://github.com/apache/apisix/issues/4924
### Issue description
I have configured the following route, wherein
1. if the upstream is down i.e it either returns 500 or 502 or 503 then
APISIX should return status as 507. But, it is not happening like that.
2. if the upstream is not down, but, it throws the error with 500 status
then also, it should give the same status code as 507.
But, in both above cases, it is not working as expected.
Route:
{
