Cannot resolve "provider" from file variable

Hey, I’m getting an error on my serverless.yml:

provider: ${file(../../commons/serverless/provider.js):default} where provider.js is : {name: 'aws'} it gets translated by sls print as:

provider:
  name:
    name: aws

package: ${file(../../commons/serverless/package.js):default} Works perfect and it’s the same .js script… Is this a bug?

Even if I do: provider: ${file(../../commons/serverless/package.js):default} it gets printed as indented inside provider.name…

https://github.com/serverless/serverless/blob/master/lib/plugins/print/print.js#L50

   // provider treatment and defaults
    this.cache.serviceProvider = service.provider;
    if (_.isString(this.cache.serviceProvider)) {
      service.provider = { name: this.cache.serviceProvider };
    }
    service.provider = _.merge(
      {
        stage: 'dev',
        region: 'us-east-1',
        variableSyntax: '\\${([^{}]+?)}',
      },
      service.provider
    );

This is definetly the issue! ${file(…)} is being treated as a string.

sls print with:

serverless.cli.consoleLog('serverless.service.provider');
  serverless.cli.consoleLog(serverless.service.provider);

in provider.js gives:

serverless.service.provider
{
  stage: 'dev',
  variableSyntax: undefined,
  name: '${file(../../commons/serverless/provider.js):default}',
  versionFunctions: true,
  remoteFunctionData: null
}
serverless.service.provider
{
  stage: 'dev',
  variableSyntax: '\\${([ ~:a-zA-Z0-9._@\'",\\-\\/\\(\\)*?]+?)}',
  name: {
    name: 'aws',
    runtime: 'nodejs10.x',
    stage: 'dev',

Bump! I am experiencing this problem as well - I am trying to find a way to omit role settings when deploying to localstack, but setting them when deploying to AWS. Building the provider block in a javascript file seemed like a good way to achieve this, but when I output a single object with something like

{
  name: 'aws',
  runtime: 'nodejs12.x',
  stage: '${opt:stage, 'dev}'
  // ... etc
}

and add the line to my serverless.yml

provider: ${file(./config/${opt:stage}.provider.js)}

when I run npx sls print the output is

provider:
  name:
    name: 'aws'
    runtime: 'nodejs12.x'
    stage: 'dev'

This seems like a really simple bug to fix - it looks like it’s expecting the provider to only ever be a string for name. But then actually parses the object being returned correctly. This is blocking us at the moment and we could really do with a quick fix

To address the question about plugins (given I mentioned the use of localstack), I have removed all plugin configurations from my serverless.yml and I get exactly the same output
