Hey all, encountering a TypeScript error I’m not familiar with. I’m not experienced enough with TS to tell if this is a user error or a bug, but I’m pretty perplexed. I’m trying to set the

defaultTags

property on an

aws.Provider

, like so:

new aws.Provider(`my-provider`, {
    ...
    defaultTags: {
        "foo": "bar"
    }
});

I’m getting a type error on

defaultTags

, stating that

Object literal may only specify known properties, and '"foo"' does not exist in type 'Input<ProviderDefaultTags>'.

A type option for

Input<T>

is

T

, and the signature of

ProviderDefaultTags

is

{[key: string]: string}

So using an arbitrary string such as “foo”:“bar” should work. What am I missing?

Remove that quotes on “foo”

^, it's a JS object declaration

new aws.Provider(`my-provider`, {
    ...
    defaultTags: {
        foo: "bar"
    }
});

No, that’s not it: this returns a similar error:

Object literal may only specify known properties, and 'foo' does not exist in type 'Input<ProviderDefaultTags>'.

This looks like what it’s expecting: https://www.pulumi.com/docs/reference/pkg/aws/provider/#providerdefaulttags

oh it wants the tags property maybe? so:

defaultTags: {
   tags: {
       foo: "bar"
   },
}

That was it. Thank you! This makes sense when reading the source code for the Provider DefaultTags type… it wasn’t clear that there was an additional layer of structure from the error message or the in-browser type hints.
