Request Transformer Advanced

Added a max_request_body_size configuration option that lets the plugin apply body transformations to request bodies that Nginx buffers to a temporary file (bodies larger than client_body_buffer_size). Previously such bodies were never read, so the configured body transformations were silently skipped and the original body was proxied upstream. The option defaults to -1, which preserves that behavior; set it to a positive byte limit to opt in (or 0 for unlimited, still bounded by Nginx’s client_max_body_size).

Fixed an issue where the plugin wouldn’t transform the response body when the upstream returned a Content-Type with a +json suffix as the subtype.

The plugin now honors the following Kong Gateway configuration parameters: untrusted_lua, untrusted_lua_sandbox_requires, untrusted_lua_sandbox_environment. These parameters apply to advanced templates (Lua expressions).

Fixed an issue that was causing some requests to be proxied with the wrong query parameters.

Added support for navigating nested JSON objects and arrays when transforming a JSON payload.

The plugin now supports vault references.

Values stored in key:value pairs in this plugin’s configuration are now referenceable, which means they can be stored as secrets in a vault.

Fixed an issue where empty arrays were being converted to empty objects. Empty arrays are now preserved.
