title: Serverless error - No file matches include / exclude patterns
body: <p>I am trying some skeleton deployment using python. Here is my serverless.yaml</p>
  <p>My folder structure is</p>
  <pre><code>serverless-test
  |_lambdas
  |____handler.py
  |_layers
  |____common
  |_________somefunction.py
  </code></pre>
  <pre><code>service: serverless-test
  
  frameworkVersion: '2'
  
  provider:
    name: aws
    runtime: python3.8
    lambdaHashingVersion: 20201221
  
    stage: test
    region: us-west-2
  
  functions:
    hello:
      handler: lambdas/handler.hello
  </code></pre>
  <p>This works fine. Now as soon as I add a layer, I get the following error</p>
  <p><code>No file matches include / exclude patterns</code></p>
  <pre><code>service: serverless-test
  
  frameworkVersion: '2'
  
  provider:
    name: aws
    runtime: python3.8
    lambdaHashingVersion: 20201221
  
    stage: test
    region: us-west-2
  
  functions:
    hello:
      handler: lambdas/handler.hello
      layers:
        - {Ref: CommonLambdaLayer}
  
  layers:
    common:
      path: layers/common
      name: common-module

  </code></pre>
  <p>I also tried adding include and exclude patterns. But it didn't solve my problem</p>
  <pre><code>service: serverless-test

  <p>I also tried being very specific</p>
