Error: Execution role must be assumable by the edgelambda.amazonaws.com

Encountered while deploying a lambda function to CloudFront

Fix

• Go to -> AMI -> Roles -> Search for the role created by Lambda during the lambda function creation.
• Select the role -> Edit Trust Relationship
• Add edgelambda.amazonaws.com under Service property as an array

"Statement": {
	"Effect": "Allow",
	"Principal": {
		"Service": ["lambda.amazonaws.com", "edgelambda.amazonaws.com"]
	},
	"Action": "sts:AssumeRole"
}
