How to fix Error: Provider produced inconsistent final plan in Terraform

TerraformINTERMEDIATEHIGHUpdated Dec 30, 2025· 199 views

This error occurs when Terraform detects a mismatch between what a provider planned to do during the plan phase and what it actually did during apply. This typically indicates a provider bug, race condition, or computed value inconsistency.

Quick fix

Fixes Error: Provider produced inconsistent final plan

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"  # Use latest stable
    }
  }
}
  1. Update the provider to the latest version
  2. Check for provider-specific GitHub issues
  3. Use ignore_changes as a temporary workaround
  4. Try running terraform apply again

Error: Provider produced inconsistent final plan

What this error means

When you run `terraform plan`, the provider calculates what changes are needed. During `terraform apply`, the provider applies those changes and reads back the resource state. If the final state differs from the planned state, Terraform raises this error. This means the provider produced an invalid new value that does not match its own plan output. This is almost always a bug in the provider itself, though it can occasionally be caused by external factors like race conditions or the provider setting unexpected default values.

Typical symptoms

  • terraform apply fails immediately after showing the plan
  • Error message says "This is a bug in the provider, which should be reported in the provider's own issue tracker"
  • The error occurs consistently with a specific resource type
  • Re-running terraform apply sometimes succeeds
  • Occurs most often with complex AWS resources like ECS task definitions, Lambda functions, or WAFv2 resources

Common causes

  1. Provider bug: The provider logic for computing the plan state differs from the actual apply behavior
  2. Computed attribute mismatch: An attribute computed by the provider during planning changes unexpectedly during apply
  3. Race condition: The remote API fails to complete the operation in time for the final read, returning incomplete or default values
  4. Default value inconsistency: The provider applies default values that were not anticipated during the planning phase
  5. Sensitive field handling: Some providers struggle with sensitive attributes and computed values combined
  6. Provider version incompatibility: An older provider version has known bugs with specific resources

How to fix "Error: Provider produced inconsistent final plan"

1Update the provider to the latest version

The most common fix is upgrading to a newer provider version, as many inconsistent final plan bugs are fixed regularly.

hcl
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"  # Use latest stable
    }
  }
}

Then run:

bash
terraform init -upgrade
terraform plan
terraform apply
2Check for provider-specific GitHub issues

Search the provider's GitHub repository for this error and your specific resource type. For AWS provider, visit: https://github.com/hashicorp/terraform-provider-aws/issues

Search terms to use:
- "inconsistent final plan" + resource name (e.g., "aws_lambda_function")
- Your specific error from the logs

If you find a matching issue, check if:
- It's been fixed in a newer version (upgrade)
- A workaround is documented
- You should report the issue if it's not already filed

3Use ignore_changes as a temporary workaround

If the issue is with a specific computed attribute, you can ignore changes to that attribute. This tells Terraform to ignore any differences that appear after apply:

hcl
resource "aws_lambda_function" "example" {
  filename      = "function.zip"
  function_name = "my-function"
  role          = aws_iam_role.example.arn
  handler       = "index.handler"

  lifecycle {
    ignore_changes = [source_code_hash]
  }
}

Replace source_code_hash with whatever attribute is causing the inconsistency. You can find this in the error message or logs.

4Try running terraform apply again

Sometimes the inconsistency is transient. Try running the same apply command again:

bash
terraform apply

If it succeeds on the second try, the infrastructure was actually created correctly despite the error. This indicates a temporary issue like a race condition.

If it fails again with the same error, proceed to the next steps.

5Import the resource and update state

If apply partially succeeded and the resource was created, you can import it into Terraform state:

bash
# Remove the resource from state
terraform state rm aws_lambda_function.example

# Import it back using its AWS ID
terraform import aws_lambda_function.example my-function

Then run plan again to see if the inconsistency persists. This refreshes the state with actual values from AWS.

6Report the bug if it's a known issue

If you've confirmed this is a provider bug not yet fixed:

1. Collect information:
 - Terraform version: terraform version
 - Provider version: terraform version -json | jq .provider_selections
 - Resource configuration (sanitized)
 - Full error output
 - Reproduction steps

2. Open a GitHub issue on the provider's repository (e.g., terraform-provider-aws)

3. Include a minimal reproducible example (MRE) that triggers the error

This helps provider maintainers prioritize and fix the issue.

7Consider rolling back provider version if urgent

As a last resort, if you're blocked, try using an older stable provider version:

hcl
required_providers {
  aws = {
    source  = "hashicorp/aws"
    version = "4.55.0"  # Use known-stable version
  }
}

Run:

bash
terraform init -upgrade
terraform plan

If this works, file a bug report that the issue exists in the newer version. This is temporary—upgrade once the provider is fixed.

Advanced notes

This error is almost always a provider bug, not a Terraform core issue. The error message "This is a bug in the provider" is Terraform's way of saying the provider violated its own contract by producing a plan that doesn't match the apply result.

Common affected resources by provider:
- AWS: aws_lambda_function (especially with skip_destroy), aws_ecs_task_definition (container_definitions), aws_wafv2_*, aws_autoscaling_group (tags)
- GCP: Generally fewer issues, but can occur with computed nested attributes
- Azure: Less common, usually version-specific

Root causes are typically:
- Computed attributes that have non-deterministic values
- JSON/list normalization differences (e.g., field order, null vs empty)
- Sensitive fields with complex update logic
- Provider not properly handling API defaults during read-back

The best long-term solution is always to upgrade the provider and file issues with maintainers.
