Debug Output

Expected Behavior

A google compute instance should have been provisioned

Actual Behavior

the terraform google provider plugin crashed

Steps to Reproduce

1. terraform apply

• #0000

[jvlake]

The same issue as above but with terraform 0.12.31 (upgrading due to public key invalidation).

PANIC: interface conversion: interface {} is *schema.Set, not []interface {}

I suspect it's a regression from 9 days ago: #8953

The GetChange from the terraform-plugin-sdk returns type getResult struct as interface{}

And this change in the PR assumes that can be cast to an array

func serviceAccountDiffSuppress(k, old, new string, d *schema.ResourceData) bool { o, n := d.GetChange(strings.TrimSuffix(k, ".#")) var l []interface{} if old == "0" && new == "1" { l = n.([]interface{})

^ I could be wrong, does that sound about right? @edwardmedia

Same issue on TFE .13.7 with this latest GCP 3.66 update:

[harroguk]

Same as @rcaril but in Terraform v0.13.5
Tested and it is working in terraform-provider-google_v3.65

[rcaril]

@megan07 - this code push did not fix the problem. Same behavior.

Hi @rcaril, I'm sorry you're experiencing the issue still. Would you be willing to share your configuration and your full debug logs so I can see what is happening? Thanks!

[rcaril]

@megan07 My log is attached.

run-mwzH4qRFxRLhDV4v-plan-log.txt

What kind of configuration are you looking for?

This is my initial setup:

terraform {
  required_providers {
    google = {
      source = "hashicorp/google"
      version = "3.66.0"
    }
  }
  backend "remote" {
    hostname     = "########"
    organization = "#####"
    workspaces {
      name = "######"
    }
  }
}

Please let me know if you need more details.

Thank you for the quick response @rcaril, I think there might be a small misunderstanding. The fix for this bug was recently merged and is still in the process of being released. From the configuration, it seems that you may still be using a version (3.66.0) that does not have this fix. The issue gets closed automatically when a fix is merged, which probably caused this confusion. Sorry about that. We are working to get this fix out in a release as soon as possible.

[rcaril]

Hi @aareet - thanks for clarifying this! I indeed did not realize that the merge would not go into your release automatically. Please keep me updated on when this has been released. Would I expect this to be version 3.67?

[aareet]

Glad we figured it out 🙂. I will certainly update this ticket once we release. We're currently expecting this to be version 3.66.1, but I will confirm once we release.

[aareet]

Hi folks, v3.66.1 with the fix for this issue is now available - please test with it and let us know if you have any feedback https://registry.terraform.io/providers/hashicorp/google/latest. Thanks for your patience.

[rcaril]

@aareet This has solved my problem, thanks!
