request-size-limiting http2 requests are not supported without content-length header about kong

[oowl]

will be fixed in #12658

[chobits]

hi this error message occurs as expected, because the Kong project expects or requires the Content-Length header to be present in this case, for functionality related to request size limiting. Otherwise request-size-limiting plugin could not work without knowing the content-lenght field

The lua-nginx-module made some changes about this behavior, see
https://github.com/openresty/lua-nginx-module/pull/2237/files#diff-e5adfbc2ed61393c8309bee7f85b858a67d5b75e4f3201610504aa571bb44323R90-R93

A bypass way is to explicitly provide the Content-Length(regardless it's zero) header for GET

This involves requesting changes. Should the plug-in not check the GET request?

[vm-001]

I'm not saying that this is a reasonable workaround. It's just a theoretical bypass based on the root cause.
