Issues setting up sentry with AWS Lambda

How do you use Sentry?

Steps to Reproduce

Hello,

I signed up for a trial of Sentry to monitor some AWS Lambdas and run into a few issues with the initial setup and after talking to support was asked to raise an issue here.

#1 - When you go through the instructions to "Automatically instrument AWS Lambda (Python)" it only detects AWS Lambda functions that are running anything below Python 3.11.

#2 - Same as #1 but in the last step when you chose a lambda to "enable for Sentry monitoring" it just gives an "Unknown Error"

#3 - I tried to follow the instructions to add the AWS Lambda Layer from the documentation and the first issue is the region selector is some horrible light grey on white that is barely readable and the second bigger issue is the Lambda layer it provides is arn:aws:lambda:ca-central-1:943013980633:layer:SentryPythonServerlessSDK:137 which is says the compatible runtimes is Python 3.11 and below so I assume that layer is out of date and hasn't been updated in awhile?

Cheers,
Paul

Expected Result

The Automatically instrument AWS Lambda (Python) wizard detects Python 3.13 and below functions and is able to add\configure the layer to monitor them.

Actual Result

Hi @paulthorburn, I am having trouble following your "Steps to reproduce." Could you please provide more context on what you did and what went wrong. For example, which instructions are you following, what code are you using to configure the Sentry SDK, etc.

Hey Daniel, as i mentioned i signed up for a trial of sentry and there appears to be 3 ways to instrument Python AWS Lambdas. Automatic, Add a Lambda Layer and Manual https://docs.sentry.io/platforms/python/integrations/aws-lambda/ . So far it has been my experience that 2 out of the 3 dont actually work. Hopefully these instructions to reproduce will clear it up.

Without touching your code

1. Sign into sentry web interface
2. Create a Project
3. Under 'Choose your platform' pick Serverless tab
4. Pick AWS Lambda (Python)
5. Hit 'Create Project
6. The 'Automatically instrument AWS Lambda (Python)' wizard will launch
7. Click 'Add Installation'
8. Click 'Go to AWS' and deploy the Cloudformation Template
9. Once complete click 'i've created the stack'
10. Enter AWS Account ID, AWS Region and click 'Next'
11. ISSUE 1 on STEP 4 it says "We found 3 functions with Node or Python runtimes" but I have several in my account. It is only detecting Lambdas running Python 3.11 and lower (see sceenshot in first post)
12. Pick a Lambda to "enable for Sentry monitoring" and click 'Finish Setup'
13. ISSUE 2 after picking a Lambda to monitor it will just show "Unknown Error" (see sceenshot in first post)

By adding the Sentry Lambda Layer to your function manually

1. Open documentation https://docs.sentry.io/platforms/python/integrations/aws-lambda/manual-layer/
2. Scroll down to 'Install The Layer'
3. There is a dropdown to 'Select the Region' and get the ARN for the Lambda Layer
4. ISSUE 1 the drop down is light grey on white and horrible to try and read
5. ISSUE 2 the ARN provided says it is compatible with Python 3.11 and it does not appear there are any new Lambda Layers

I also noticed that this document https://docs.sentry.io/platforms/python/integrations/aws-lambda/container-image/ points to this repo https://gallery.ecr.aws/sentry/sentry-python-serverless-sdk with a container image that hasn't been updated in 3 years.

Thank you for the additional details, @paulthorburn.

Regarding the first and last issues you listed, where you noticed that the AWS Lambda Layer is only compatible with Python versions 3.11 and lower: this is indeed expected behavior, since the AWS Lambda Layer only supports Python 3.7-3.11. However, we can add support for Python 3.12 and 3.13. I opened #3946 to do this.

Regarding the "Unknown error" you observed, please open an issue in the getsentry/sentry repository.

Lastly, regarding the dropdown being light grey on white, I will raise an issue for this in the getsentry/sentry-docs repository for this.

I am closing this issue in favor of the issues listed above; please let us know if you have any further questions.

Also, regarding this:

I also noticed that this document https://docs.sentry.io/platforms/python/integrations/aws-lambda/container-image/ points to this repo https://gallery.ecr.aws/sentry/sentry-python-serverless-sdk with a container image that hasn't been updated in 3 years.

The docs page you linked has a deprecation notice at the top stating that the Python AWS Lambda Container Image is deprecated. So, that is probably why the container image has not been updated in three years
