so it's only available as an output, and not say for console log?

im creating a bunch of Identities, but I need the output of the identity.principalId, I was trying to create an object of all the identities to export out

Yes - this is where you use `.apply`. To log it out, you can do `.apply(console.log)`. To transform the value to use in some other way, do `.apply(id =&gt; “hello: “ + id)`

this is the base idea im going for: ```for role in roles:
  for region in regions:
     let uai = new azure.msi.UserAssignedIdentity()
     output[`${role}:${region}`] = uai.principalId

export let output_mapping = output;```

That should work fine as is. What do you see when you do `Pulumi stack output`?

```                  - uai:[object Object]:resources   : [
                  -     [0]: "st:inf3bootstrapwus:bootstrap"
                  -     [1]: "kv:inf3bootstrapwus"
                    ]```

thats the preview output, let me try `pulumi stack output`

```"weu":{"uai:[object Object]:resources":["st```

Not sure I quite follow how that’s related to the code snippet above - do you have the complete (or a small repro) code that is hitting this?

sure, running couple tests now that i know it should work

i was trying to use the principal id as an interpolated string template var

this worked, where uai.principal gets assigned as the value pushed to an array

```Utils._add_to_output(output_list, role, env_id, region, `kv:${vault_name_parsed}`, uai.principalId)```

```Utils._add_to_output(output_list, role, env_id, region, `uai:${String(uai.principalId)}:resources`, `st:${storage_account_name_parsed}:${container.name}`)```

where I was trying to use the output in a string interpolation

here's the diff on the output after running it both ways

```- st:inf3bootstrapwus:bootstrap: [
-     [0]: "81f5de7e-9f4a-404b-bfd4-c4e478e975c8"
]
+ uai:[object Object]:resources: [
+     [0]: "st:inf3bootstrapwus:bootstrap"
]```

it's a 1-1 relationship though, so i think i'm OK either way

i realize this is probably an odd situation, but this UAI + Azure thing has been a nightmare lol
