AWS CloudFormation error: Properties validation failed for resource LAMBDAXXXX with message: #/Code: expected type: JSONObject, found: String

During a AWS CF deployment I got the following error:

Properties validation failed for resource LAMBDAXXXX with message: #/Code: expected type: JSONObject, found: String

After struggling for over 4 hours, it turned out that the issue was that the path was not correct in the CF Template!!!

  LAMBDAXXXX:

    Type: "AWS::Lambda::Function"

    Properties:

      FunctionName: LambdaIngestXXXX

      Code: "../lambda/lambda_function_folderpath_xxxx/"

      Handler: "lambda_function.lambda_handler"

      Layers:

        - !ImportValue LAYERPYREQUESTS

        - !ImportValue LAYERAWSWRANGLER

The error: "#/Code: expected type: JSONObject, found: String" it turns out translates to "your path ../lambda/lambda_function_folderpath_xxxx/" is wrong!!!

How I hate CloudFormation!!!

Hope this saves someone else time!
