status code of a `http_client` under output.

I am encountering an issue when attempting to capture the http_status_code from an HTTP endpoint using Benthos. Despite configuring the extract_headers to include the http_status_code, the logged output consistently returns for the status code.

this is the method is tried.
i used "http_status_code" because i saw in the code, the http_status_code is being set in the repo:
https://github.com/redpanda-data/benthos/blob/main/internal/httpclient/client.go#L219

I have a benthos/connect config like this:

http:
  address: 0.0.0.0:4195
input:
  http_server:
    address: ""
    path: /endpoint
    allowed_verbs:
      - POST
output:
  http_client: 
    url : <endpoint> (configured to give 200 for now)
    verb : POST
    propagate_response : true
    extract_headers : 
      include_prefixes: [ "http_status_code" ]
  processors :
    - log:
        fields_mapping: |
          root.event_type = this.type
          root.event_id = this.id
          root.status_code = meta("http_status_code")

the output log i'm recieving is :

 path=root.output.processors.0 status_code="<nil>"

can anyone please guide me here ?

Start with the reproduction configuration in the issue and inspect internal/httpclient/client.go around line 219, where http_status_code is set. Trace how extract_headers and propagate_response expose that value to meta("http_status_code") in the output processor. Done means the configured endpoint's status code appears in the log instead of nil.
