The role defined for the function cannot be assumed by Lambda

Question

I\'m getting the error \"The role defined for the function cannot be assumed by Lambda\" when I\'m trying to create a lambda function with create-function command.

Answer 1

It could be that the Lambda is missing an execution role. Or this role has been deleted.

In console you can see the status at Lambda > Functions > YourFunction > Permissions. Even an IAM empty role with no policies is enough to make it work.
