Version is not a property. It is a part of the JSON blob that gets passed to

assumeRolePolicy

.

@salmon-ghost-86211

assumeRolePolicy

is defined as follows:

readonly assumeRolePolicy: pulumi.Input<string | PolicyDocument>;

You can either pass a full JSON string blob, or use the

PolicyDocument

type which offers you Intellisense completion in the editor. I chose that and then

Version

is a property defined as:

Version: Input<"2008-10-17" | "2012-10-17">;

Yes. You are correct. In that case

Version

and `Statement`are properties under

assumeRolePolicy

. The below worked for me.

const testRole = new aws.iam.Role("testRole", {
    assumeRolePolicy: {
        Version: "2012-10-17",
        Statement: [
            {
                "Action": "sts:AssumeRole",
                "Principal": {
                "Service": "<http://ec2.amazonaws.com|ec2.amazonaws.com>"
                },
                "Effect": "Allow",
                "Sid": ""            }
        ]
    },
    tags: {
        "Purpose": "Just testing",
    }

Strange. The error was actually in my

Condition

. Once I had that fixed, the error on

Version

disappeared also.

I think I actually prefer that layout over the JSON blob.

@salmon-ghost-86211 in the snippet you posted, you can even replace the String keys within your

Statement

with property names. In short: remove the quotes in the key names.

Yes. I copied an example and modified it quickly, but definitely a good reminder. Thanks.

I saw this myself recently. I think there must be a TypeScript compiler bug (and somewhat recent regression) here. For now, you can insert a cast like

as any

.
