[ERROR] UnboundLocalError: local variable 'span_kind' referenced before assignment

[M3gar00]

Issue Type: Bug

I get the following error when I attempt to run a lambda with the aws-otel-lambda layer activated. The ARN of the layer is: arn:aws:lambda:${var.aws_region}:901920570463:layer:aws-otel-python38-amd64-ver-1-9-1:2

The full error message I get is:

[ERROR] UnboundLocalError: local variable 'span_kind' referenced before assignment
Traceback (most recent call last):
  File "/opt/python/wrapt/wrappers.py", line 578, in __call__

    kind=span_kind,

Could you provide any additional code example?

[M3gar00]

I'm not sure what code example I can provide; I do not have access to the code from which this error is being emitted. I used AWS resources to implement this as an Auto-Instrumented layer on my Lambda application.

@vasireddy99
Could you let me know when a version that fixes this issue will be released?

[vasireddy99]

Hi @sungwonh Thanks for reaching out, I have checked with the opentelemetry-python-contrib maintainers through the CNCF slack channel. We may expect the new release with the fix by end of next month. Once the v0.30b.0 release is available. We can update the dependencies in OpenTelemetry-lambda and follows the lambda layer release. I will update info here if there are any changes as we go on :-)

Hi @vasireddy99, looks like v0.30b1 of opentelemetry-python-contrib is already available. Any plans on releasing a new layer with the fix for this? Thanks!

[vasireddy99]

Hi @juanitosvq , The lambda layers with this fix are expected to be available in May. shall provide more updates as we go on.

[M3gar00]

@vasireddy99 -- It looks like the fix is not yet in for this. Am I missing something?

[vasireddy99]

HI @M3gar00, Please expect the fix to be available with the new lambda layers which are expected to released in this month.

[vasireddy99]

Update : The lambda Layer with OTel python 1.11.1 that includes the fix for this issue is available.

@vasireddy99 The new OTel lambda layer is working from our side, and the problem has been fixed! Thanks for fixing the issue 👍
