• URL: Add vm_error field for transactions in Block Replay stacks-core#6575
• Merged: 2025-10-29

What Changed

Added a new vm_error field to the block replay RPC endpoint transaction responses. This optional field contains runtime error messages when a transaction execution fails, providing better debugging information for failed transactions.

Documentation Impact

Files Needing Updates

• /docs/reference/rpc-api.md - Update block replay endpoint documentation to mention the new vm_error field

Recommended Changes

In /docs/reference/rpc-api.md

Section: Block Replay RPC endpoint (around line 242-244)

Since the block replay endpoint documentation references the OpenAPI spec, consider adding documentation about this field or ensuring the OpenAPI spec properly documents the vm_error field:

Add a note about the vm_error field:
vm_error field added: Block replay responses now include an optional vm_error field in transaction objects that contains error messages when transaction execution fails, helping with debugging failed transactions.

Note: This change is part of ongoing improvements to the block replay endpoint. See also PR #6638 which adds additional fields to this endpoint.

Priority

Medium - API enhancement that helps developers debug transaction failures
