Failed (104: Connection reset by peer) while reading response header from upstream

When the schema increases, getting 502 Bad Gateway error. And the log is as below
failed (104: Connection reset by peer) while reading response header from upstream, client: 172.18.0.6, server: , request: "GET /en/admin/config/graphql/servers/manage/test/explorer HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm.sock:", host: "test.ddev.site", referrer: "https://test.ddev.site/en/admin/config/graphql"

If we remove some of the fields in the schema, site is again up and running.

Anybody facing this issue? Thanks in advance.

We ran into this as well. We tried reverting to a previously known "Good" version of our schema, but still saw 502s. When we tried using an empty schema with a single field, our endpoint was up again.

We tried the patch described here: #1268, and that seems to have fixed it for us, including being able to use our updated schema that originally gave us 502.

@c-theriot Thanks for the quick response. Yes, this fixed my issue. Hopefully this is not affecting anything in the graphql module workflow.
