How to fix planned value for a non-computed attribute in Terraform

First, identify which version of the provider you're using. Run:

terraform version

Look for the provider version in the output. This error is often fixed in newer provider versions. Check the provider's changelog to see if this issue has been addressed.

Update your versions.tf or main.tf to use a newer provider version:

terraform {
  required_providers {
    provider_name = {
      source  = "provider/name"
      version = ">= X.Y.Z"  # Use latest stable version
    }
  }
}

Then run:

terraform init -upgrade
terraform plan

Most provider maintainers have resolved these schema inconsistencies in recent releases.

From the error message, identify which resource and attribute is causing the issue. The warning will show:

- .ATTRIBUTE_NAME: planned value cty.VALUE for a non-computed attribute

Note the attribute name so you can decide if it's critical or if you can work around it.

If the problematic attribute is optional and you're not explicitly setting it, try removing it from your configuration:

resource "provider_resource" "example" {
  # Remove the problematic_attribute if not needed
  other_attribute = "value"
}

If the attribute isn't required and you're letting it default, removing it may eliminate the warning.

If you must use the attribute, explicitly set it in your configuration to match what the provider defaults to:

resource "provider_resource" "example" {
  problematic_attribute = false  # Or true, depending on the default
}

This ensures the configuration matches what the provider will set in state, eliminating the inconsistency.

If upgrading doesn't fix the issue, report it to the provider's issue tracker with:

- Provider name and version
- Terraform version
- The exact error message including the attribute name
- Minimal configuration that reproduces the issue
- OS and architecture

For HashiCorp providers, use: https://github.com/hashicorp/terraform-provider-NAME/issues

For community providers, check their repository for issue guidelines.

Subscribe to the provider's release notes and watch for fixes to data consistency errors. Many providers are actively migrating from terraform-plugin-sdk (SDKv2) to terraform-plugin-framework, which has stricter data consistency enforcement and fewer of these issues.

Check the provider's roadmap or migration plan to see when this update is expected.
