Cannot deploy aws sam stack due to Handler not found error - aws-cloudformation

Question

I am having issues deploying a lambda with a handler in a nested directory using sam.
I perform the following steps:
package:
sam package --template template.yaml --output-template-file packaged.yaml --s3-bucket
Creates a packaged.yaml that I use in the next step.
deploy:
aws cloudformation deploy --template-file /Users/localuser/Do/learn-sam/dynamo-stream-lambda/packaged.yaml --stack-name barkingstack

I believe you have to put everything except the resource type under "Properties".
Your function declaration should be:
PublishNewBark:
Type: AWS::Serverless::Function
Properties:
FunctionName: publishNewBark
CodeUri: .
Handler: src/index.handler
Role: "<ROLE_ARN>"
Description: Reads from the DynamoDB Stream and publishes to an SNS topic
Events:
- ReceiveBark:
Type: DynamoDB
Stream: !GetAtt BarkTable.StreamArn
StartingPosition: TRIM_HORIZON
BatchSize: 1
