I’m having some trouble with

aws.iam.getPolicyDocument

. I need to set a KMS Key in the

resources

field, but I get an error

error TS2322: Type 'Output<string>' is not assignable to type 'string'.

. It seems the interface expects a string

resources?: string[];

. Is there a way to convert the

Output<string>

to

string

? The only thing I see is to not use the

aws.iam.getPolicyDocument

. I see other thread here with a similar issue, but no answer was given: https://pulumi-community.slack.com/archives/CJ909TL6P/p1558459714056300
