The Terraform AWS provider plugin crashes during plan or apply operations. This is typically caused by version-specific bugs, memory constraints, or problematic resource configurations. Most cases are resolved by upgrading to a patched provider version or downgrading to a stable release.

Error: The terraform-provider-aws plugin crashed!

What this error means

When Terraform executes, it communicates with the AWS provider plugin via an RPC protocol. A plugin crash means the provider process terminated unexpectedly, usually due to a panic error in the provider code, insufficient system memory, or an incompatibility with a specific AWS resource configuration. This is always indicative of a bug within the provider itself and should be reported to HashiCorp.

Typical symptoms

  • Terraform plan or apply terminates with 'plugin crashed' error message
  • Error output includes panic stack trace with memory or nil pointer dereference details
  • Issue occurs consistently with specific resource types or configurations
  • Problem appears in CI/CD pipelines but works locally (or vice versa)
  • Crash happens during the refresh phase or when managing large numbers of resources

Common causes

  1. Version-specific bugs in specific AWS provider releases (e.g., v5.32.0, v6.8.0, v6.13.0)
  2. Memory exhaustion when using many provider aliases or very large configurations
  3. Nil pointer dereference bugs in certain AWS resources (S3 tables, SageMaker, etc.)
  4. Integer overflow or type conversion errors when parsing large values
  5. Memory leaks in long-running provider processes
  6. Incompatibility between specific Terraform and provider versions

How to fix "Error: The terraform-provider-aws plugin crashed!"

1Check your current provider version

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

bash
terraform version

Look for the AWS provider version in the output. Common problematic versions include v5.32.0, v6.0.0, v6.8.0, and v6.13.0.

2Check the HashiCorp support article for your version

Visit the HashiCorp Help Center and search for your specific provider version. The error message typically indicates which version you're running. Check if there's a known issue and recommended fix:

https://support.hashicorp.com/hc/en-us/articles/25111858689939

If your version is listed as having a known crash, move to step 3.

3Upgrade or downgrade the provider version

Update your Terraform configuration to use a stable provider version. In your main.tf or versions.tf, set a provider constraint:

hcl
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.31.0"  # Use a known stable version
    }
  }
}

Then run:

bash
terraform init -upgrade
terraform plan

Alternatively, if you want the latest version, try:

hcl
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 5.32.1"  # Skip the buggy v5.32.0
    }
  }
}
4Clear Terraform cache and reinitialize

Clear the Terraform cache to ensure the new provider version is downloaded:

bash
rm -rf .terraform
terraform init

Then run a plan to see if the crash persists:

bash
terraform plan
5Identify the problematic resource (if crash persists)

If the crash continues, examine the stack trace in the error output to identify which resource is causing it. Common culprits include:

- aws_s3_bucket and aws_s3_object (with v6.13.0)
- aws_s3tables_table and aws_s3tables_table_bucket (with v6.0.0, v6.8.0)
- aws_lb_target_group, aws_subnet, aws_security_group
- aws_cognito_user_pool, aws_dynamodb_table_item

Note which resource(s) are mentioned in the stack trace.

6Workaround for destroy operations

If the crash only occurs during terraform destroy, try this workaround:

1. Comment out or remove the resource causing the crash from your Terraform configuration
2. Run terraform init (to re-detect resources)
3. Run terraform plan and terraform apply (to delete the offending resource)
4. Then proceed with destroying the rest of your infrastructure:

bash
terraform destroy
7Report the issue to HashiCorp

If none of the above steps resolve the crash, or if your version is not listed as having a known bug, report it to the Terraform AWS provider repository:

https://github.com/hashicorp/terraform-provider-aws/issues

Include:
- Your Terraform version (terraform version)
- Your AWS provider version
- The exact error message and stack trace
- The Terraform configuration snippet that triggers the crash
- Your operating system and architecture

This helps HashiCorp identify and fix the bug faster.

Advanced notes

Memory Issues: If the crash occurs when managing large numbers of resources or using multiple provider aliases, it may be due to memory exhaustion. Each provider alias consumes roughly 100MB of memory. Consider reducing the number of aliases or splitting your configuration across multiple workspaces.

Environment Differences: Some crashes only occur in CI/CD environments (GitHub Actions, GitLab CI) due to limited memory. Verify your runner has sufficient RAM (at least 4GB recommended) and consider reducing terraform parallelism with -parallelism=2 to lower memory usage.

Regex Cache Issue: AWS provider versions before v5.14.0 had inefficient regex caching that could cause memory leaks. Ensure you're using v5.14.0 or later if experiencing long-running operations.

Schema Caching: Terraform v1.6.0 and later support cached provider schemas, significantly reducing memory consumption on subsequent runs. Upgrade Terraform if you're on an older version.
