Not able to attach EventBridge Schedule to Lambda Function in AWS SAM

Question

I'm unable to attach an EventBridge Schedule to a lambda function in AWS SAM.

Here is the section of my SAM template that intends to attach a schedule to the Lambda function:

TestLambda:
    Type: AWS::Serverless::Function
    Properties:
      FunctionName: TestLambda
      CodeUri: test_directory/
      Handler: test_file.lambda_handler
      Runtime: python3.8
      Role: !Ref LambdaApiRole
      Events:
        TestLambdaCron:
          Type: Schedule
          Properties:
            Schedule: rate(1 day)

This is the error I get while deploying the template:

Embedded stack <stack ARN> was not successfully updated. Currently in UPDATE_ROLLBACK_IN_PROGRESS with reason: The following resource(s) failed to create: [TestLambdaTestLambdaCron].

A solution would be much appreciated, thanks in advance!

PS: LambdaApiRole is defined in the template and can be referenced in the function (working fine), it's when TestLambdaCron is added when the issues occur

The AWS SAM CLI version I am working on is: SAM CLI, version 1.37.0
