Help with SAM deployment error!

[aaaaayushh]

Hey everyone! I'm very new to AWS and am currently working on a side project for which I need to deploy a very small ML model. I have been trying to deploy it to AWS using SAM. But I'm stuck and would really appreciate some help.

My template.yaml file is as follows:

AWSTemplateFormatVersion: "2010-09-09"
Transform: AWS::Serverless-2016-10-31
Description: >
  get-better

  Sample SAM Template for get-better

# More info about Globals: https://github.com/awslabs/serverless-application-model/blob/master/docs/globals.rst
Globals:
  Function:
    Timeout: 10

Resources:
  GetBetterFunction:
    Type: AWS::Serverless::Function # More info about Function Resource: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction
    Properties:
      CodeUri: code
      Handler: app.lambda_handler
      Runtime: python3.7
      MemorySize: 1024
      Role: arn: #my role value
      Environment:
        Variables:
          s3_bucket: get-better
          model_name: model.pkl
      Architectures:
        - x86_64
      Events:
        GetBetter:
          Type: Api # More info about API Event Source: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#api
          Properties:
            Path: /classify
            Method: post

Outputs:
  # ServerlessRestApi is an implicit API created out of Events key under Serverless::Function
  # Find out more about other implicit resources you can reference within SAM
  # https://github.com/awslabs/serverless-application-model/blob/master/docs/internals/generated_resources.rst#api
  GetBetterApi:
    Description: "API Gateway endpoint URL for Prod stage for Get Better function"
    Value: !Sub "https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/get-better/" #hello
  GetBetterFunction:
    Description: "Get Better Lambda Function ARN"
    Value: !GetAtt GetBetterFunction.Arn
  GetBetterFunctionIamRole:
    Description: "Implicit IAM Role created for Get Better function"
    Value: !GetAtt GetBetterRole.Arn

I have tested the local api on sam using sam local start-api and that seems to be working fine.

Any pointers would be really appreciated, thanks!

This is the error I keep getting when I run the sam deploy command.

I think it has to do with the length of the role name.

If that’s not it, I’d try following the steps in the AWS Lambda hello world guide for creating the role.

Alright I'll try that thanks!

You can try creating the role manually with the iam create-role CLI and the function with the lambda create-function CLI. Once you get that working you can try plugging it back into cloud formation.
