Problem

when running http_server source with tls and alpn_protocols, protocol negotiation does not happen and it always defaults to http/1.1

Configuration

[sources.dummy_logs]
type = "http_server"
address = "0.0.0.0:443"
tls.alpn_protocols = ["h2"]
tls.ca_file = "/Users/anil.gupta/localHttpsFiles/certs/myCA.pem"
tls.crt_file = "/Users/anil.gupta/localHttpsFiles/certs/localhost.crt"
tls.enabled = true
tls.key_file = "/Users/anil.gupta/localHttpsFiles/certs/localhost.key"
tls.key_pass = ""
tls.verify_certificate = false
tls.verify_hostname = false
# Print parsed logs to stdout
[sinks.print]
type = "console"
inputs = ["dummy_logs"]
encoding.codec = "json"

Version

vector 0.31.0 (x86_64-apple-darwin 0f13b22 2023-07-06 13:52:34.591204470)

Debug Output

Example Data

after running http_server if you use curl we see that protocol negotiation did not happen

curl -k -vv -X POST https://localhost:443 -d "hello"
Note: Unnecessary use of -X or --request, POST is already inferred.
