OpenTelemetry trace error occurred. HTTP status client error (404 Not Found) for url (http://localhost:4318/) #155

Closed EMUNES closed 1 month ago

I found this error when testing the example axum_oltp. I have deployed jaeger on docker following this repo's instruction. However, it reports this error on port 4318, which is the OLTP http port.

I found a possible related issue about this here. But I have no idea how to make configurations for this crate to fix this problem.

I don't know which crates you talk (they are several on this repo), but configuration could be done by environment variables a subset of https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/ (also look at the names in uppercase in the log above)
