Hi there! I’m trying to setup AWS cost budgets with tag filters, but can’t get what’s the expected format for the

CostFilters

map.

_, err = budgets.NewBudget(ctx, "test-budget", &budgets.BudgetArgs{
    BudgetType: pulumi.String("COST"),
    CostFilters: pulumi.StringMap{
        "TagKeyValue": pulumi.String(`["stack$test"]`),
    },
    LimitAmount: pulumi.String(budgetAmount),
    LimitUnit:   pulumi.String("USD"),
    TimeUnit:    pulumi.String("MONTHLY"),
})

Diagnostics:
  aws:budgets:Budget (test-budget):
    error: aws:budgets/budget:Budget resource 'test-budget' has a problem: Attribute should be a list. Examine values at 'Budget.CostFilters'.

Tried the example in the docs: https://www.pulumi.com/docs/reference/pkg/aws/budgets/budget/#example-usage, but just get a compilation error:

Invalid composite literal type: String
Missing key in the map literal

Anyone has a working example?
