Error when using external config files

[mtford90]

I have the following line in my config:

provider:
  name: aws
  # ...
  environment: ${file(../../serverless/consumer_env.yml)}

When I run serverless deploy I see the following:

 Cannot create property 'SERVERLESS_EXPRESS_PLATFORM' on string '${file(../../serverless/consumer_env.yml)}'

Hi, @mtford90,
I'm looking at it right now

@mtford90

• I did the exact same configuration, and it didn't throw any error
• the function is deployed with all environment variables.

I'd like to investigate more,
Can you share the versions of your local serverless-cli and serverless-express ?

[mtford90]

Hey @iliasbhal - appreciate the speed!

• serverless-express: 2.0.11
• serverless-cli: 1.38.0
• Node: 8.10.0

@mtford90 I'll try to take time to fix this bug soon
In the meantime, you can do this quick hotfix:

Assign the variables to the function instead of the provider.
I tested it and it's working great. but it's a hotfix, I'll push something soon

functions:
  express:
    handler: src/lambda.handler
    memorySize: 2048
    environment:  ${file(../../serverless/consumer_env.yml)}
