AWS SAM Local and docker lambda: keep getting Unable to import module lambda_function: no module named lambda_function,

Question

Edit 2: The main reason was that I had several DOCKER environment variables that called my function calls to redirect to the remote Docker host, and not for SAM Local. As soon as I turned them off, the functions started to work.

Edit: I cloned docker-lambda and tried to run one of my examples and get the same error.

docker run --rm -v "$PWD":/var/task lambci/lambda:python3.6

{"errorMessage": "Unable to import module 'lambda_function'"}

I am trying to configure SAM Local using the Python lambda function and continue to give up on the import error of the module in the header.

My template.yaml looks like this:

AWSTemplateFormatVersion : '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Resources:
  ProposalsTable:
    Type: "AWS::Serverless::SimpleTable"
  AddProposal:
    Type: "AWS::Serverless::Function"
    Properties:
      Handler: lambda_function.lambda_handler
      Runtime: python3.6
      Policies: AmazonDynamoDBFullAccess
      Environment:
        Variables:
          TABLE_NAME: !Ref ProposalsTable
      Events:
        Vote:
          Type: Api
          Properties:
            Path: /proposals
            Method: get

I have lambda_function.py in the same folder as template.yaml.

I run: sam local start-apiand it starts normally:

Mounting lambda_function.lambda_handler (python3.6) at http://127.0.0.1:3000/proposals [GET]

Then I do:

curl http://127.0.0.1:3000/proposals

"" :

Unable to import module 'lambda_function': No module named 'lambda_function':

, template.yaml, : Handler: index.handler. index.js, handler, exports.handler = () => {}
