@mariomac: I am looking at 401 Unauthorized errors in the latest release code [Beyla v1.2.1], am I missing anything?

ERROR: 2024/02/18 05:06:10 failed to upload metrics: failed to send metrics to https://otlp-gateway-prod-ap-south-1.grafana.net/otlp/v1/metrics: 401 Unauthorized

Grafana Beyla version used https://github.com/grafana/beyla/releases/download/v1.2.1/beyla-linux-amd64-v1.2.1.tar.gz

Reproducing error: followed steps mentioned in this link Grafana Beyla to upload OTEL traces to Grafana cloud which is static single instance agent basis.

@NiranjanHD please check that, in the Grafana cloud API key, you are copying the raw API key and not the generated OTEL Headers ("Authorization: Basic ....").

As an alternative, try using the OTEL_EXPORTER_OTLP_HEADERS, as stated in the steps here:
