Lambda Collector Configuration

[DockerIsBAd]

It is unclear throughout the documentation about what types of exporters are supported. Are they the same as a normal dockerized collector? Because all you mention is 'Without an environment variable being set for your exporters the default configuration only supports emitting data using the debug exporter.' Well I am using sentry as exporter and when testing my lambda I get the error of:

failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:\n\n* error decoding 'exporters': unknown type: "sentry" for id: "sentry" (valid values: [prometheusremotewrite logging otlp otlphttp]); Post "http://127.0.0.1:9001/2020-01-01/extension/init/error\": net/http: invalid header field value for "Lambda-Extension-Function-Error-Type"",
"errorCauses": [
{
"error": "failed to get config: cannot unmarshal the configuration: 1 error(s) decoding:\n\n* error decoding 'exporters': unknown type: "sentry" for id: "sentry" (valid values: [prometheusremotewrite logging otlp otlphttp])"
},
{
"error": "Post "http://127.0.0.1:9001/2020-01-01/extension/init/error": net/http: invalid header field value for "Lambda-Extension-Function-Error-Type""
}
]
}

So the error message and the documentation seem to contradict themselves.

@open-telemetry/lambda-extension-approvers WDYT?

To clarify - This is about a Lambda collector layer I attempted to set-up.

hey @DockerIsBAd if you are registered with CNCF slack (via https://slack.cncf.io/), you can join #otel-faas and ask the experts there.

I assume the problem is that sentry isn't supported by the collector lambda layer. Perhaps you could seek support from Sentry on how to handle this scenario?
