requests with multipart/form-data payload are not being streamed

[RAVIPATISRIVIDYA]

We are sending a request with the multipart/form-data content type, for a file upload. Buffering has been disabled for the route using this annotation - konghq.com/request-buffering: 'false'.

However, the request is not being streamed to the upstream service as expected. Instead, Kong appears to be reading the entire request body content before proxying it to the upstream.

The API only has the ACL, authentication, and rate-limiting plugins enabled, which, to my knowledge, do not enforce buffering.

Can anyone help on this.
