# Config Version Error • AI Agent SDK

# ConfigVersionError

> Defined in the [**config**](../modules/config) module.

<Badge color="blue">AI Agent</Badge>

Raised when a config carries a `config_version` this build can't handle.

Two cases, both operator-actionable rather than silently corrupting data:

* the stamp is a version *newer* than :data:`GATEWAY_CONFIG_VERSION` — an
  older binary must not downgrade / migrate a config written by a newer
  one (that would drop keys the newer schema added), so migration refuses;
* the stamp is present but not a non-boolean integer — a malformed stamp
  (`true`, `"1"`, `1.0`) is a mistake, not "current", so it is
  rejected instead of being treated as version 1 via `True == 1`.
