Need support to enforce HTTP/1.1 API call in http component in benthos

[jeetvachhani285]

While I am calling API using http component i am getting stream error: stream ID 6107; HTTP_1_1_REQUIRED; received from peer error in benthos.

It will be working fine if there is an intermediary, such as a proxy, firewall, or security software (e.g., Netskope). It might be possible because it will be enforcing or preferring HTTP/1.1 over HTTP/2 but without that it throws error.

Config file:

http:
    url: https://<cloud-instance>/BeyondTrust/api/public/v3/Auth/SignAppIn
    verb: POST
    rate_limit: api_ratelimit
    timeout: 45s
    extract_headers:
      include_prefixes:
        - set-cookie

Here you can see the error which i am getting.

level=error msg="Failed to call SignIn API due to https://<cloud-instance>/BeyondTrust/api/public/v3/Auth/SignAppIn: Post \"https://<cloud-instance>/BeyondTrust/api/public/v3/Auth/SignAppIn\": Post \"https://<cloud-instance>/BeyondTrust/api/public/v3/Auth/Connect/Token\": stream error: stream ID 521347; HTTP_1_1_REQUIRED; received from peer" @service=benthos label="" path=root.input.broker.inputs.0.processors.3.switch.processors.2.catch.0

So is there any way to by which we can enforce HTTP/1.1 for API call may be by adding some an advanced flag for this in benthos?
