Explanation
The Lambda function must have permission to call EventBridge APIs, which is granted by adding an IAM policy to the function’s execution role that allows putting events to the target event bus. In addition, because the event bus is in a different AWS account, the event bus must have a resource-based policy that explicitly allows the source AWS account (where the Lambda function runs) to put events to it.
