Good Morning, I'm experiencing an issue where an ASG I'm creating is saying the Launch Template isn't valid with the following error:

Value () for parameter groupId is invalid.

I've got a simplified version of my code below. Can someone tell me what I'm missing? I've tried everything including

vpcSecurityGroups

,

securityGroupNames

,

networkInterfaces:securityGroups

as well as doing getSecurityGroup requests instead.

const group1s = new aws.ec2.SecurityGroup("secgrp-1s", {
  vpcId: defaultVpcId,
  description: "Enable HTTPS access",
  ingress: [{
    protocol: "tcp",
    fromPort: 443,
    toPort: 443,
    cidrBlocks: ["0.0.0.0/0"],
  }],
  egress: [{
    protocol: "-1",
    fromPort: 0,
    toPort: 0,
    cidrBlocks: ["0.0.0.0/0"],
  }],
}, {dependsOn: [appVpc]})

const launchTemplate = new aws.ec2.LaunchTemplate("spot-lt", {
  imageId: "ami-0f93c02efd1974b8b",
  instanceType: instanceType ?? "t3.micro",
  vpcSecurityGroupIds: [group1s.id],
}, {dependsOn: [group1s]})

const autoScalingGroup = new aws.autoscaling.Group("spot-asg", {
  desiredCapacity: desiredCapacity ?? 1,
  minSize: minSize ?? 1,
  maxSize: maxSize ?? 1,
  availabilityZones: ["us-east-1a", "us-east-1b"],
  mixedInstancesPolicy:{
    instancesDistribution: {
      onDemandBaseCapacity: onDemandBaseCapacity ?? 1,
      onDemandPercentageAboveBaseCapacity: onDemandPercentageAboveBaseCapacity ?? 0,
      spotAllocationStrategy: "lowest-price",
    },
    launchTemplate: {
      launchTemplateSpecification:{
        launchTemplateId: launchTemplate.id,
        
      },
    },
  },
}, {dependsOn: [launchTemplate, group1s]})

Going a little nuts figuring out what I missed

maybe you have oversimplified it but I do not see you providing

groupId

at all hence empty value is invalid

There is no value allowed for Group ID that I can find for

aws.ec2.LaunchTemplate

https://www.pulumi.com/registry/packages/aws/api-docs/ec2/launchtemplate/#inputs

right, in TS it is also ensured that all required parameters are present

Full error:

creating Auto Scaling Group (spot-asg-232abd0): ValidationError: You must use a valid fully-formed launch template. Value () for parameter groupId is invalid. The value cannot be empty

so error is in last statement, and

launchTemplate: {
      launchTemplateSpecification:{
        launchTemplateId: launchTemplate.id,
        
      },
    },

is malformed this is a tricky one, do you see launch template created? I also noticed that you have dependency loop for

autoScalingGroup

.. I do not think you need dependsOn statement here at all

Sorry, that look is not actually there in my actual code.

I wish I ever deployed ec2 ASGs with pulumi, but gone serverless long time, sorry about that

how is the

launchTemplateSpecification

malformed? I'm not doing any overrides, so there shouldn't be anything there.

what I usually do in this situation - go with debugger inside pulumi internals and see actual checks

I wish I ever deployed ec2 ASGs with pulumi

Don't worry about it, appreciate the help. I'm trying to come over from terraform so expecting to hit roadblocks

or you also can download some any minimal working example and try to find differences with your code

yea, I've done that. Also run through pulumi's AI & Copilot with no help too. That's why I came here

if you believe this is bug in error message it would be great to report to pulumi for bugfix
