[Feature]: Increase the Size of the API Response Header

[ame-appsmith]

Is there an existing issue for this?

• I have searched the existing issues

Summary

When running a REST API for which the response header is larger than 8 KB (which is the normal size as per this Wikipedia article), the following error gets returned:

Your API failed to execute:
org.springframework.web.reactive.function.client.WebClientRequestException: HTTP header is larger than 8192 bytes.

The same API works fine in tools such as Postman and ReqBin.
This blocks users who run APIs with response headers >8 KB since the API will always fail with the above-mentioned error.
More info in this Slack thread.

Why should this be worked on?

Increasing the API response header size would improve the user experience for users who are required to run APIs with response headers >8KB.
