Packaging layers using exclude/include patterns displays deprecation warning

Serverless Framework
1

I recently upgraded Serverless from version 1.63.0 to 2.32.1. My project uses a lambda layer which is configured in a subfolder so it can be packaged separately. The serverless.yml file includes this layer definition:

layers:
  appsync:
    path: layers/appsync-layer
    compatibleRuntimes:
      - nodejs12.x
    package:
      include:
        - node_modules/**

When I deploy the project now, I get the following error message:

Serverless: Deprecation warning: Support for "package.include" and "package.exclude" will be removed with next major release. Please use "package.patterns" instead
            More Info: https://www.serverless.com/framework/docs/deprecations/#NEW_PACKAGE_PATTERNS

I know this deprecation message is due to the layer configuration because I do not use package.include or package.exclude anywhere else in the serverless.yml file. I modified the layer configuration as such:

layers:
  appsync:
    path: layers/appsync-layer
    compatibleRuntimes:
      - nodejs12.x
    package:
      patterns:
        - 'node_modules/**'

However, I then get the following warning message:

Serverless: Configuration warning at 'layers.appsync.package': unrecognized property 'patterns'
Serverless:  
Serverless: Learn more about configuration validation here: http://slss.io/configuration-validation
Serverless:  
Serverless: Deprecation warning: Starting with next major, Serverless will throw on configuration errors by default. Adapt to this behavior now by adding "configValidationMode: error" to service configuration
            More Info: https://www.serverless.com/framework/docs/deprecations/#CONFIG_VALIDATION_MODE_DEFAULT

I know there are many open issues about packaging lambdas and layers on the Serverless Github repository, including:

Am I seeing a bug that should be reported? I know that for now the original configuration with the include can be used.
