# strategy_spec_level_unsupported

The Strategy Spec was saved for a FORGE_API level this version of Forge does not run.

## What happened

The `forge_api` of the spec is a level this Forge does not run: one that is retired, or one newer than this version knows. The save is refused with 400.

## What to do

Save the spec at a level the message lists.

## Example

```json
{
  "error": "This strategy was saved for FORGE_API 3. This version of Forge runs FORGE_API 1.",
  "code": "strategy_spec_level_unsupported",
  "path": "forge_api"
}
```
