Hi all! I am trying to create a folder inside an S3 bucket. The name of the bucket is taken from a stack reference, and I need to concatenate its name with the new folder name So I did applyT on the stack reference and passed the concatenated variable - the issue is that I still get a pointer value and not the string value:

bucketName = stackReference.GetStringOutput(pulumi.String("BucketName"))
appliedBucket := bucketName.ApplyT(func(name string) string {
	return name
}).(pulumi.StringInput)

resourceName := fmt.Sprintf("%v/%s/", appliedBucket, "testFolder")
key := fmt.Sprintf("testFolder")

// Create S3 folder
bucket, err := s3.NewBucketObjectv2(ctx, resourceName, &s3.BucketObjectv2Args{
	Key:    pulumi.String(key),
	Bucket: appliedBucket,
	Tags:   tags,
})

So when I do pulumi up I get this:

Type                      Name                                      Plan       Info
     pulumi:pulumi:Stack       audio-player-sdk-staging                             1 message
 +   └─ aws:s3:BucketObjectv2  {0xc000782d90}/testFodler/

@prehistoric-sandwich-7272 if you’re going to do it this way, you need to create the bucketObject inside the apply

@billowy-army-68599 Something like this?

//Create folder
folder := bucketname.ApplyT(func(appliedBucket string) *s3Pkg.BucketObjectv2 {
   folder, err := s3Pkg.NewBucketObjectv2(ctx, resourceName, &s3Pkg.BucketObjectv2Args{
      Key:    pulumi.String(key),
      Bucket: pulumi.String(appliedBucket),
   })
   if err != nil {
      log.Fatalf("Got error while trying to create new S3 bucket! Error: %s", err)
   }
   return folder
})

log.Println(folder)

yes

@billowy-army-68599 Does it make sense that I get no resource created when I put it inside the applyT? because when I run it I get nothing 😞

it won’t show up in preview, but again - i don’t think this is the correct solution

@billowy-army-68599 what solution do you recommend?

if it’s a stringOutput, you should be able to pass the name directly.

@billowy-army-68599 still doesn’t work 😞 tried like this:

bucket := stackReference.GetStringOutput(pulumi.String("ProgrammaticSdkBucketName"))
appliedBucket := bucket.ApplyT(func(name string) string {
  return name
}).(pulumi.StringOutput)

folderName := "myFolder"
_, err := s3.NewBucketObjectv2(ctx, folderName+"/"+ctx.Stack(), &s3.BucketObjectv2Args{
  Key:    bucket,
  Bucket: pulumi.String(fmt.Sprintf("%s/%v", folderName, appliedBucket)),
})

and I get:

error: program failed: waiting for RPCs: marshaling properties: awaiting input property key: failed to convert <nil> to string
    exit status 1

    Provided name to get stack reference from: matanchetz//staging

    error: an unhandled error occurred: program exited with non-zero exit code: 1
