so, it appears that there is some type of issue with

aws.ec2.SpotInstanceRequest

where as if you utilize a launchTemplate, it is failing to actually bring in the launchTemplate and execute it. Instead, I end up getting errors. However, from the console I can actually create the SpotInstance from the template without issue. Anyone else face something similar? Will likely be opening up an issue on github but wanted to check here first before I do that. Example:

const launchTemplate = new aws.ec2.LaunchTemplate("spot-launch-template", {
  namePrefix: "xxxxxxx-",
  ebsOptimized: "true",
  monitoring: {
    enabled: true,
  },
  networkInterfaces: [{
    networkInterfaceId: eni.id,
    deviceIndex: 0,
    networkCardIndex: 0,
  }],
  maintenanceOptions: {
    autoRecovery: "default",
  },
  tagSpecifications: [{
    resourceType: "instance",
    tags: {
      Name: "xxxxxx-instance",
    },
  }],
  imageId,
  userData: userData.apply(ud => Buffer.from(ud).toString("base64")),
  instanceType: "t4g.nano",
  updateDefaultVersion: true,
}, { dependsOn: [eipAssociation] });

const spotInstance = new aws.ec2.SpotInstanceRequest("spot-instance", {
  launchTemplate: {
    id: launchTemplate.id.apply(id => id),
    version: "$Latest",
  },
  spotType: "persistent",
}, { dependsOn: [launchTemplate] });

Results in:

error:   sdk-v2/provider2.go:472: sdk.helper_schema: requesting EC2 Spot Instance: operation error EC2: RequestSpotInstances, https response error StatusCode: 400, RequestID: xxxxxxxxxx, api error MissingParameter: The request must contain the parameter instanceType: provider=aws@6.52.0

Ok, so maybe

instanceType

could be required, so after adding that:

error:   sdk-v2/provider2.go:472: sdk.helper_schema: requesting EC2 Spot Instance: operation error EC2: RequestSpotInstances, https response error StatusCode: 400, RequestID: xxxxxxxxx, api error MissingParameter: The request must contain the parameter imageId: provider=aws@6.52.0
