Error on Lambda test: no such file or directory

[michaelfecher]

I'm getting an error in my Lambda when including the self-built lambda layer:

{
  "errorMessage": "RequestId: 16cb64d6-a350-4939-8dd8-9148f8d934f1 Error: fork/exec /opt/extensions/opentelemetry-lambda-extension: no such file or directory",
  "errorType": "Extension.LaunchError"
}

Steps:

1. Makefile build

ZIP File of step1 has the content:

extensions/opentelemetry-lambda-extension

2. Makefile publish Layer is created in the account + region

3. adding layer to a lambda function with hello-world content with NodeJS Runtime 12

4. adding the collector.yaml in the root of the function content:

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: localhost:55680

exporters:
  awsxray:
  awsemf:

service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [awsxray]
    metrics:
      receivers: [otlp]
      exporters: [awsemf]

5. setting env variable: OPENTELEMETRY_COLLECTOR_CONFIG_FILE=/var/task/collector.yaml

6. hit test

Hi, today (very similar test) - i think it is same error:

Collector extension in opentelemetry-lambda repo currently only has otlp receiver and exporter, and no any processor included. If need components other than them you have to build your custom Collector extension layer. Please refer AWS solution: https://github.com/aws-observability/aws-otel-collector/tree/main/pkg/lambdacomponents https://github.com/aws-observability/aws-otel-lambda/blob/main/patch-upstream.sh#L3-L7
