interface {} is nil error when scaling default node pool in kubernetes cluster

I'm using terraform with your provider to manage a cluster, and have encountered an error during the apply stage whenever I try to change the number of nodes in the cluster's default node pool. Note that the configuration change does occur, but terraform doesn't recognise that and thinks the apply failed due to the error.
Output from terraform:

Error: The terraform-provider-civo_v1.0.18 plugin crashed!
This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Using dashboard.civo.com works :|

Fun fact, the cluster scaled properly.. just my Terraform Cloud Run failed with above message
alejandrojnm commented
Hi @Xzelsius I will check this
lblackstone commented
@alejandrojnm I noticed that you marked this issue as complete. Is a fix included in a release yet? Thanks!
alejandrojnm commented
I will check this again, you still have the problem ???

One of our users ran into a similar panic, but it looks like that was using v1.0.24 of terraform-provider-civo, so I'm not sure if it was fixed in a subsequent release?
nicolasochem commented
@alejandrojnm hi, did you have a chance to look? I am still blocked from resizing my node pools from pulumi (which is using this code). thanks in advance.
alejandrojnm commented
Hi sorry for the delay in this issue, I will take a look today

For the record, I just received this error using v1.0.29 on Terraform Cloud:

The node pool did successfully resize, just like previously reported.
