OpenTelemetry in Phoenix - Not Getting HTTP Attributes in Spans

Questions / Help
1

I am trying to implement OpenTelemetry in my Phoenix app and am following this Getting Started Guide

I followed all the steps mentioned, and when I try to log spans in the console (as shown here: Try it out), I only see Ecto-related attributes in the span. However, I do not see any HTTP attributes (such as method, URL, or status code).

Here’s an example of the span I’m getting:

{span,199985616168702119339811124307741799904,15622809613813534696,
      {tracestate,[]},
      undefined,<<"kayaan_prints.repo.query:users">>,client,-5764607449421824,
      -5764607449372672,
      {attributes,128,infinity,0,
                  #{source => <<"users">>,
                    'db.instance' => <<"kayaan_prints_dev">>,
                    'db.name' => <<"kayaan_prints_dev">>, 'db.type' => sql,
                    'db.url' => <<"ecto://localhost">>,
                    'db.system' => postgresql, total_time_microseconds => 4812,
                    decode_time_microseconds => 0,
                    idle_time_microseconds => 980275,
                    query_time_microseconds => 2048,
                    queue_time_microseconds => 2764}},
      {events,128,128,infinity,0,[]},
      {links,128,128,infinity,0,[]},
      undefined,1,false,
      {instrumentation_scope,<<"opentelemetry_ecto">>,<<"1.2.0">>,undefined}}

It seems like opentelemetry_ecto is working fine, but I am not getting any HTTP-related telemetry data.

Does anyone know what could be causing this? Do I need to add an additional instrumentation library for HTTP spans in Phoenix? Any help would be appreciated!
