Plugin did not respond - rediscloud_subscription interface {} is nil not string
Hi Folks,
I previously ran a successful apply with this terraform - I ran a terraform destroy and have been getting an error trying to reapply ever since.
I've tried version bumping the providers (this started on 1.5.0) and the usual reinitialising etc.
Terraform Version
$ terraform -v
Terraform v1.7.0
on darwin_arm64
+ provider registry.terraform.io/hashicorp/google v4.84.0
+ provider registry.terraform.io/hashicorp/google-beta v5.25.0
+ provider registry.terraform.io/redislabs/rediscloud v1.6.0
Affected Resource(s)
Please list the resources as a list, for example:
- rediscloud_subscription
Terraform Configuration Files
resource "rediscloud_subscription" "subscription" {
name = var.gcp_project_id
payment_method = "marketplace"
memory_storage = "ram"
allowlist {
security_group_ids = [""]
cidrs = [for _, subnet in data.google_compute_subnetwork.subnets : subnet.ip_cidr_range]
}
cloud_provider {
provider = "GCP"
region {
region = var.gcp_region
networking_deployment_cidr = var.deployment_cidr
}
}
creation_plan {
memory_limit_in_gb = var.memory_limit_gb
quantity = 1
replication = true
throughput_measurement_by = "operations-per-second"
throughput_measurement_value = var.throughput_ops
modules = var.redis_modules
}
}

Error: The terraform-provider-rediscloud_v1.6.0 plugin crashed!
Expected Behavior
A new subscription should be created in rediscloud
Actual Behavior
An error was received interface conversion: interface {} is nil, not string
Steps to Reproduce
terragrunt apply
Important Factoids
Running via terragrunt;
$ terragrunt -v
[INFO] Getting version from tgenv-version-name
[INFO] TGENV_VERSION is 0.53.8
terragrunt version v0.53.8
Resolution
While the subscription already existed - I changed the variable redis_modules being used to set the modules argument in the creation plan to have a default value of [""] - a list containing an empty string.
After following through the stacktrace I realised the provider was unable to handle this and attempted to update the redis_modules argument to have a default value of [] instead (an empty list) which solved the problem.
I'll attempt to add some error handling to this in the coming days to make things a little more graceful.
Hi @cameron-mills, looks like you've found the problem!
Requesting a module named "" is/should be invalid but the error around it has been addressed.
Please give 1.8.0 a spin if you need any other new features (please take a look at the changelog) and let us know if you run into any issues.
Cheers!
