Search for the role associated with your Lambda function and click on it. 4. Click on the "Attach policies" button. 5. In the search bar, type "AWSLambdaBasicExecutionRole" and select it from the list. 6. Click on the "Attach policy" button to grant the necessary permissions to your Lambda function. 7. Retry the PutSubscriptionFilter operation in CloudWatch Logs. By attaching the "AWSLambdaBasicExecutionRole" policy to your Lambda function's role, you provide the necessary permissions for CloudWatch Logs to execute your function successfully.
