How do I set a map with `pulumi config set`? I got the command to work but running the program failed:
```> pulumi config set --path 'aws:defaultTags.tags' '{"user:Project": "my_project"}'
error: pulumi:providers:aws resource 'default_6_9_0' has a problem: could not validate provider configuration: Attribute must be a map. Check `pulumi config get --path aws:defaultTags.tags````

other things I've tried:
```&gt; pulumi config set --path 'aws:defaultTags.tags.["user:Project"]' my_project
error: invalid configuration key: could not parse aws:defaultTags.tags.["user:Project"] as a configuration key (configuration keys should be of the form `&lt;namespace&gt;:&lt;name&gt;`)```
--
```&gt; pulumi config set --path 'aws:defaultTags.tags.user:Project' my_project
# same error as above```
--
```&gt; pulumi config set --path 'aws:defaultTags.tags.test' true
error: defaultTags.tags: expected a map```

Hello <@U03CLBPHR0D>, the following commands:
```$ pulumi config set --path 'aws:defaultTags.tags.key' value
$ pulumi config set --path 'aws:defaultTags.tags.otherkey' othervalue```
give me the following stack config:
```config:
  aws:defaultTags:
    tags:
      key: value
      otherkey: othervalue```
The problem for you is that your `key` contains a colon (`user:Project`). This seems to confuse our argument parsing. Can you file an issue for this?

 Hey Ringo, that’s the same format I used for the last command, but I still got the error. This was with a blank yaml so that might be the difference
