MIGRATION ISSUE: `imagebuilder.LaunchTemplateConfiguration.SetDefaultVersion` not sending `false` value

[ewbankkit]

Pre-Migration Checklist

• I've read the Migration Guide.
• I've checked AWS Forums and StackOverflow for similar migration issues.

Go Version Used

go1.22.5

Describe the Migration Issue

If the bool SetDefaultVersion field of the imagebuilder.LaunchTemplateConfiguration structure is set to false, that value is not being serialized and sent to the AWS service. The means that it is impossible to update the value from true to false via v2 of the Go SDK.

Code Comparison

v1

	apiObject := &imagebuilder.LaunchTemplateConfiguration{}

	if v, ok := tfMap["launch_template_id"].(string); ok && v != "" {
		apiObject.LaunchTemplateId = aws.String(v)
	}

	if v, ok := tfMap["default"].(bool); ok {
		apiObject.SetDefaultVersion = aws.Bool(v)
	}

v2

	apiObject := &awstypes.LaunchTemplateConfiguration{}

	if v, ok := tfMap["launch_template_id"].(string); ok && v != "" {
		apiObject.LaunchTemplateId = aws.String(v)
	}

	if v, ok := tfMap["default"].(bool); ok {
		apiObject.SetDefaultVersion = v
	}

Hi @ewbankkit ,

Thanks for raising this once again.
I will re-raise this issue internally to see how we should go about fixing this.
