Failed to restore the function {lambda-name}: The function does not have permission to access the specified image.

The lambda in question is image-based, which depends on ECR. It does not seem to be clear that what permissions from ECR are required for the lambda role nor the permissions is required to be attach to ECR. The problem remain, even thou the permissions had been applied accordingly based on the given documentation: https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-images.html#gettingstarted-images-permissions

The more concerning thing is the root cause of image-based lambda required to be restore. Is it normal for image-based lambda, to require restore after certain time period or certain conditions? If so, what are the conditions that will require the lambda to be restore?
