Telemetry not working with OTLP HTTP mode #17479
Description
What happened?
When configuring an OTLP endpoint in Gemini CLI settings with HTTP protocol (not gRPC), it leads to an HTTP error and not metrics, logs or traces are push to the endpoint.
Gemini CLI is not using the correct paths to use the OLTP HTTP mode.
This closed PR fixed the bug: #16836
What did you expect to happen?
I expect to see data in my OpenTelemetry backend.
