Denied Access to logs:CreateLogStream action as Root User

Hello.

I am new to AWS and was writing a function in AWS Lambda to create a log group and log stream. When I test in AWS Lambda, the log group is successfully created, but an error occurs when trying to create a log stream for that log group. As the root user, for some reason, I am getting a Client Error: Access Denied Exception because my root user "is not authorized to perform: logs:CreateLogStream" on the log_stream resource "because no identity-based policy allows the logs:CreateLogStream action." However, when I code something similar in my local IDE with Boto3, everything works as expected.

Appreciate any help!
