AWS IAM Lambda "is not authorized to perform: lambda:GetFunction" - amazon-web-services

Question

When I have my IAM Policy for my lambda execution role set to:
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"lambda:GetFunction"
],
"Resource": [
"*"
],
"Effect": "Allow"
}
]
}
I get this error:
[AccessDeniedException: User:
arn:aws:sts::xxx:assumed-role/supercoolsoftware-dev-us-west-2-lambdaRole/supercoolsoftware-dev-addEmail
is not authorized to perform:
lambda:GetFunction on resource:
arn:aws:lambda:us-west-2:xxx:function:supercoolsoftware-dev-dailyEmail]
However, when I set the policy to:
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"lambda:*"
],
"Resource": [
"*"
],
"Effect": "Allow"
}
]
}
The error is gone... What else do I need to add?

Answer 1

Figured it out. Apparently the SDK uses "lambda:GetFunctionConfiguration" as well. Once I included that it all worked.
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"lambda:GetFunction",
"lambda:GetFunctionConfiguration"
],
"Resource": [
"*"
],
"Effect": "Allow"
}
]
}

For anyone getting this error after the alexa.design/cli tutorial,
ASK_CLI_USER is not authorized to perform: lambda:GetFunction on resource
The issue for me was not "lambda:GetFunctionConfiguration" but instead the Resource line below it due to the "ask-" prefix:
"Resource": "arn:aws:lambda:*:*:function:ask-*"
Changing it to this solved my issue:
"Resource": "arn:aws:lambda:*:*:function:*"

The solution is as CamHart said, but there is a twist.
They apparently renamed these permissions. You must now use
lambda:InvokeFunction and lambda:InvokeFunctionConfiguration instead of lambda:GetFunction and lambda:GetFunctionConfiguration
Exemple
JSON
"Statement": [
{
"Effect": "Allow",
"Action": [
"lambda:GetFunction",
"lambda:GetFunctionConfiguration"
],
"Resource": [
"*"
]
}
]
YAML
Statement:
- Effect: Allow
Action:
- lambda:InvokeFunction
- lambda:InvokeFunctionConfiguration
Resource: '*'
