TypeError : Cannot read property "Properties" of undefined

[hstefanov]

TypeError : Cannot read property "Properties" of undefined in \lib\stackops\lambdaRole.js:38:11 when role attribute is not included as root property in serverless.yml file.

How to reproduce:

Include serverless-aws-alias plugin and leave lambda role ARN in the function explicitly without overriding with global value.

service: name: api

provider: name: aws

functions: api: handler: handler name: name role: arn:aws:iam::account:role/rolename events:

    - serverless-pseudo-parameters
    - serverless-aws-alias

  exclude:
    - "*.swp"

How did you solve your issue @hstefanov ?

[raymercb]

This may be related to the role at the function level.

I have the same problem in a project with two functions. Each function has its own role. No role at the provider level. Without the plugin, it works fine.

If you only have one function in the serverless.yml, try setting the role at the provider level.

[jacobsidford]

Issue still present. Running serverless: 1.16.2 serverless-aws-alias: 1.8.0

@raymercb 's suggestion of setting role at the provider level worked for me

[emmaLP]

Has anyone managed to get this working?
