Hi there, How are you supposed now to successfully access a component’s value passed to a custom

ComponentResource

(in my use case, I need a bucket’s name) ? I tried to define an arg like

aws.s3.bucket

,

string

,

pulumi.Input<string>

,

pulumi.Input<aws.s3.bucket>

, I tried to pass the whole bucket object or the bucket name directly, I tried to convert the input as an output, I tried to apply, interpolate, whatever, all I get when I want to use the name is :

Calling [toString] on an [Output<T>] is not supported.
    
    To get the value of an Output<T> as an Output<string> consider either:
    1: o.apply(v => `prefix${v}suffix`)
    2: pulumi.interpolate `prefix${v}suffix

Thanks

pulumi.Input<string>

is usually best, but you can also pass the full

aws.s3.Bucket

object. Can you share your code with how you're trying to use the bucket name?

something like

const cdn = new CDN('website-cdn', {
  bucket: myBucket,
}, { provider })

where

myBucket

is an

aws.s3.Bucket

but I also tried directly

myBucket.bucket

with

export interface CdnArgs {
  // choose your poison
  bucket: string | aws.s3.Bucket | pulumi.Input<string | aws.s3.Bucket>;
}

export class CDN extends pulumi.ComponentResource {
  constructor (
    name: string,
    args: CdnArgs,
    opts?: pulumi.ComponentResourceOptions,
  ) {
    super(`${pulumi.getProject()}:CDN`, name, {}, opts)

  // use it here

  }
}

Here's an example.

@gentle-diamond-70147 thanks, but nope, already tried that (was actually my first try).

That works for me - I just deployed it.

I should mention I don’t use the value directly, I use it in a template literal

It does. In that case, you do need to use

.apply()

or

.interpolate

to use the value.

already tried that too, same error

Can you provide your full code? 🙂

Ok I found out what’s wrong trying to make an mve. The problem was not in the args, but in the name of the component (the error was giving no clue though), because in my final code I do a template literal for the name with another output (which I dropped for the examples I gave you…)

Ah, sorry. I did miss that in the code you initially provided. Resource and component names must be "hard coded" strings, not interpolated from resource outputs.

ok, that works. I was over-thinking this one 😅 Thanks again for your help @gentle-diamond-70147 ! 🙏

You're welcome!
