Hello, Having error on creating AutoScaling Group...

Hello, Having error on creating AutoScaling Group in pulumi when using ### With Latest Version Of Launch Template Error says "Attribute must be a list. Examine values at asg.tags" and actual error message is as below Error message : 
Diagnostics:
aws:autoscaling:Group (my-auto-scaling-group):
error: aws:autoscaling/group:Group resource 'my-auto-scaling-group' has a problem: Attribute must be a list. Examine values at 'my-auto-scaling-group.tags'.
my code looks like this from screenshot below and displaying the error message below. I am using Pulumi with Typescript. Any help to resolve the error is much appreciated. I did upgrade sdk using latest version of aws sdk (npm install -g @nice-addition-43900/aws@latest )

this works for me:
Copy code
tags: [{
            key: "environment",
            value: "test",
            propagateAtLaunch: true,
        }]

if this is still happening, could you provide a 
pulumi about
d
ah yeah, I got this too… I don’t have any tags specified and I’m getting this error
something related to autotagging?
f
curious what your 
pulumi
and 
pulumi-aws
versions are

wtf…?
ok so I think I know what was going on in the first place—we’re using https://github.com/tlinhart/pulumi-aws-tags and I didn’t realize
so that was setting tags
now that I’ve upgraded everything I think it’s just a different error that I’m getting
(with a horrible, unhelpful stacktrace)
f
that is uh... yeah, that's a lot 🙂
d
Ok fixed that error… it was either my version of pulumi or probably more likely an outdated version of pulumi-aws-tags
f
innnnnnteresting! so you're all good now that everything's upgraded, including 
pulumi-aws-tags
?
d
yup! thank you… well at least I can run 
pulumi preview
… hopefully 
up
will work too, but if it doesn’t it certainly won’t be because of this tags issue 🙂 thank you for your help!
f
bwahahahahhaaaargh 😄
d
yup I guess other people ran into it… makes sense since the Group has a concept of “propagate_at_launch”
f
hey @quiet-painter-19715 perhaps this was your issue as well?
aha, yeah, it's not a simple key/value
q
Hello @future-hairdresser-70637 Its the similar issue I am having, but I added a work around when tags are coming from aws:asg
f
👍 Glad you got it working!
q
But I am still wondering why autoscaling group tags have to marked unsupported tags _UNSUPPORTED_RESOURCE_TYPES = {"awsautoscaling/groupGroup"}
f
I think it's because it's not a typical key/value set; there's an additional property 
propagate_at_launch
which complicates matters for providers. I haven't looked deeply at it though
d
so most resources take tags like: 
{"foo_key": "bar_value"}
. ASGs take it like 
{"key": "foo_key", "value": "bar_value", "propagate_at_launch": true}
. 
pulumi-aws-tags
doesn’t handle the case. I opened an issue to discuss better handling: https://github.com/tlinhart/pulumi-aws-tags/issues/37
I think it’d make sense for there to be a configuration option to handle this if you do want your ASGs to use auto tags
q
Yeah I agree if we can make it as a configuration option
