Import error - ImportError: cannot import name 'std_to_otel' from 'opentelemetry._logs'
Describe your environment
OS: Linux Python version: python3.12 SDK version: 1.25.0 API version: 1.25.0
What happened?
I have OTEL layer auto instrumented lambda in AWS region us-west-2 which uses OTEL layer - arn:aws:lambda:us-west-2:901920570463:layer:aws-otel-python-amd64-ver-1-29-0:2
The traces were correctly being sent to OTEL collector -> dynatrace until 21st July, but we noticed no tracing after that. I checked the logs for CloudWatch and started seeing this error as attached in - log-events-viewer-result.8.csv
log-events-viewer-result (8).csv
We tried updating the lambda layer to the latest version [arn:aws:lambda:us-west-2:901920570463:layer:aws-otel-python-amd64-ver-1-32-0:2] but still see same issue
Steps to Reproduce
Auto instrumented Lambda python function.
Expected Result
Should be able to see traces in Dynatrace.
Actual Result
No tracing.
Additional context
No response
Would you like to implement a fix?
None

@xrmx - What could've possibly changed inside the layer which is causing this issue, since we haven't updated the layer.
This breakage was part of this https://github.com/open-telemetry/opentelemetry-python/pull/4649
otel-lambda already bumped the dependencies: https://github.com/open-telemetry/opentelemetry-lambda/blob/main/python/src/otel/otel_sdk/requirements.txt to the latest ones Probably mix of dependencies issue?
Thanks @emdneto. So, looks like this has already been fixed. If I point to latest otel layer - arn:aws:lambda:us-west-2:901920570463:layer:aws-otel-python-amd64-ver-1-32-0:2 I should not be seeing this issue but still not working for me.
I also am using opentelemetry-api package which was earlier on lower version but now its pointing to the latest 1.36.0.
My python version is 3.9, in process of upgrading it but it is supported.
Not able to understand what could be causing this issue still.
@emdneto @xrmx
It looks like dependencies are not updated inside the OTEL layer I am suspecting it is still having older version of the SDK - Do we know who's responsible for updating the later ?
