attribute mismatch: associate_public_ip_address (true vs. 1)

[rhettg]

My VPC state got stuck in some weird state due to a mismatch between true and 1:

~ module.vpc_lab.aws_instance.vpn
    associate_public_ip_address: "true" => "1"
    source_dest_check:           "true" => "1"

~ module.vpc_lab.aws_route53_record.vpn0
    records.#: "" => "<computed>"

When applying:

Error applying plan:

1 error(s) occurred:

* aws_instance.vpn: diffs didn't match during apply. This is a bug with Terraform and should be reported as a GitHub Issue.

Please include the following information in your report:

    Terraform Version: 0.6.14
    Resource ID: aws_instance.vpn
    Mismatch reason: attribute mismatch: associate_public_ip_address
    Diff One (usually from plan): *terraform.InstanceDiff{Attributes:map[string]*terraform.ResourceAttrDiff{"source_dest_check":*terraform.ResourceAttrDiff{Old:"true", New:"1", NewComputed:false, NewRemoved:false, NewExtra:interface {}(nil), RequiresNew:false, Type:0x0}, "associate_public_ip_address":*terraform.ResourceAttrDiff{Old:"true", New:"1", NewComputed:false, NewRemoved:false, NewExtra:interface {}(nil), RequiresNew:false, Type:0x0}}, Destroy:false, DestroyTainted:false}
    Diff Two (usually from apply): *terraform.InstanceDiff{Attributes:map[string]*terraform.ResourceAttrDiff(nil), Destroy:false, DestroyTainted:false}

This is in us-east-1. Maybe there is some API bug?

I'm seeing something similar. us-west-2 here.

~ module.redis_arm.aws_instance.redis_master
    disable_api_termination:                   "false" => "0"
    ebs_optimized:                             "true" => "1"
    monitoring:                                "true" => "1"
    root_block_device.0.delete_on_termination: "true" => "1"
    source_dest_check:                         "true" => "1"

~ module.redis_arm.aws_instance.redis_slave.0
    disable_api_termination:                   "false" => "0"
    ebs_optimized:                             "true" => "1"
    monitoring:                                "true" => "1"
    root_block_device.0.delete_on_termination: "true" => "1"
    source_dest_check:                         "true" => "1"

~ module.redis_arm.aws_instance.redis_slave.1
    disable_api_termination:                   "false" => "0"
    ebs_optimized:                             "true" => "1"
    monitoring:                                "true" => "1"
    root_block_device.0.delete_on_termination: "true" => "1"
    source_dest_check:                         "true" => "1"

Possibly related to setting the following on my aws_instance resources?

  lifecycle {
    ignore_changes = [ "user_data" ]
  }

If I try to apply, I get this:

This should be fixed in the latest version of Terraform.
