My lambda uses requests. I have one package.zip file that works correctly when I deploy using cdk. I’ve tried multiple things to reproduce the package.zip I have. All of the ways I’ve tried fail. Once the lambda is deployed with my other attempts of recreating my package.zip, I get the error

"errorMessage": "Unable to import module 'lambdaHanlder': No module named 'requests'"

I use pip install --target=package -r requirements.txt to create the package folder and then zip the files inside of that folder.

my requirements.txt file:

constructs>=10.0.0,<11.0.0
requests

Creation of lambda layer and lambda:

const lambdaLayer = new lambda.LayerVersion(this, 'layer', {
        code: lambda.Code.fromAsset('package.zip'),
        description: 'Libraries needed.'
      });

    const fn = new lambda.Function(this, 'function', {
      runtime: lambda.Runtime.PYTHON_3_9,
      code: lambda.Code.fromAsset('lib/lambda'),
      handler: 'lambda.handler',
      description: new Date().toString(),
      layers: [lambdaLayer]
    })

I’m working on creating the readme for my project and would like to be able to reproduce the pacakge.zip file that works. I have one package.zip file that allows my lambda to use requests, so I know this way can be done and works. I don’t know how I created the package.zip, besides some combination that I’ve been attempting.

I’ve used different python versions using pyenv. 3.7, 3.8, 3.9, 3.11, and 3.12. I’ve tried switching my node version too.
