Cannot set property 'pythonRequirements' of undefined

[petergaultney]

I am probably just misunderstanding how layers are supposed to work.

I have

functions:
  getWorkflow:
    handler: vision_workflow.api.AS_LAM_getWorkflow
    memorySize: 1024
    layers:
      - {Ref: PythonRequirementsLambdaLayer}

custom:
  pythonRequirements:
    layer: true
    slim: true
    useDownloadCache: true
    noDeploy: []

and I get this:

Serverless: Packaging Python Requirements Lambda Layer...

  Type Error ---------------------------------------------

  Cannot set property 'pythonRequirements' of undefined

     For debugging logs, run again after setting the "SLS_DEBUG=*" environment variable.

  Stack Trace --------------------------------------------

This had to do with not having Serverless >= 1.34 installed. The documentation should be updated to note the new version required.
