get-session-token not returning valid token

[moldach]

I get an error trying to run funclist <- sapply(list_functions(), get_function_name)

Error in lambdaHTTP(verb = "GET", action = act, query = query, ...) :
Forbidden (HTTP 403).

I downloaded and isntalled the Amazon Command Line Interface, configured it and requested a session token:

aws sts get-session-token --duration-seconds 129600

This returns:

{
    "Credentials": {
        "SecretAccessKey": "mysecretkey", 
        "SessionToken": "mytoken", 
        "Expiration": "2019-12-22T10:06:25Z", 
        "AccessKeyId": "mykey"
    }
}

Now I place these into R and try and run the command:

Sys.setenv("AWS_ACCESS_KEY_ID" = "myKey",
           "AWS_SECRET_ACCESS_KEY" = "mysecretkey",
           "AWS_DEFAULT_REGION" = "us-east-1",
           "AWS_SESSION_TOKEN" = "mytoken")

library("aws.lambda")

# get list of all current functions
funclist <- sapply(list_functions(), get_function_name)

It looks like The security token is invalid. How do I get a valid token?
