I gave the <http://pulumi.com/ai|pulumi.com/ai> a try and it came with a conclusion to create a custom aws provider where one can define a set of default tags and use this provider for all resources.

This would merge the resource tags with those from the aws provider

<@UGGRPRNJE> this looks like you’re marshalling the array of tags into the wrong type?

it should end up being
```map[team]application-team```

for example, if I do `export const defaultTags = config.requireObject&lt;{ [key: string]: string }&gt;("defaultTags");` I get
```Outputs:
  + defaultTags: [
  +     [0]: {
          + team: "application-team"
        }
  +     [1]: {
          + environment: "dev"
        }
  +     [2]: {
          + cost-center: "123456"
        }
    ]```

Hi <@UCWG26BH7> I get the same output, but the route53 block still fails
```...
tags: {
   ...defaulttags,
   Name: fqdn,
}```
The complete error message is:
```Diagnostics:
  aws:route53:Zone (storeapplication):
    error: aws:route53/zone:Zone resource 'applicationZone' has a problem: '' expected type 'string', got unconvertible type 'map[string]interface {}', value: 'map[team:application-team]'. Examine values at 'Zone.Tags["0"]'.```
Exporting the defautlTags gives me the same result like you got:
```Outputs:
  + defaultTags: [
  +     [0]: {
          + team: "application-team"
        }
  +     [1]: {
          + environment: "dev"
        }
  +     [2]: {
          + cost-center: 123456
        }
    ]```

i think this can be fixed by just changing your defaultTags to just be an object/map, not an array
```config:
  aws:region: eu-central-1
  my-application:defaultTags:
    team: application-team
    environment: dev
    cost-center: "123456"```

Thanks for the suggestion, will give it a try and report.
