# Error: The plan output exceeds the maximum allowed size of 4 MB

- **ID:** `terraform/plan-output-too-large`
- **Domain:** terraform
- **Category:** runtime_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The Terraform plan file is too large due to many resources or large state data, exceeding the 4 MB limit for plan serialization.

## Version Compatibility

## Workarounds

1. **Reduce the number of resources in a single plan by using Terraform modules or splitting into separate configurations. For example, break a large VPC setup into smaller modules.** (85% success)

2. **Use 'terraform plan -out=plan.tfplan' and then 'terraform show plan.tfplan' to view the plan, instead of relying on the full output.** (90% success)

## Dead Ends

- **** — Increasing the timeout or retrying the plan does not reduce the plan size. (95% fail)
- **** — Splitting the configuration into multiple workspaces without reducing resource count still results in large plans. (75% fail)
