Error: Keyword [object Object] is not a valid identifier

My commit hook fails with any combination of message. It looks like it's an error integrating with the AJV module. Here are some commits I've tried plus the stack trace.

`git commit -m "chore: lint on commit"`
`git commit -m "foo: this will fail"`
`git commit -m "feat(thing): makes updates to the thing"`

```
xxx/node_modules/ajv/lib/keyword.js:30
throw new Error('Keyword ' + keyword + ' is not a valid identifier');
^
Error: Keyword [object Object] is not a valid identifier

husky - commit-msg hook exited with code 1 (error)
```

## Expected Behavior

I'd expect to see the commits succeed and fail based on their validity.

## Current Behavior

It looks to me like a there's a parsing error. The stack trace makes me think it's a problem integrating with the AJV library. I'm working in a private repo so I can't share the source code. 😅
