Hi, i seem not to be able to write any schemas with caveats. Am I missing a step? I attached a sample schema and the error:
```
caveat my_test(b bool) {
    b
}

definition abc {

}

definition test {
    relation abc: abc with my_test
}
```
```
FTL failed to write schema error="rpc error: code = FailedPrecondition desc = could not lookup caveat `my_test` for relation `abc`: caveat `my_test` not found"
```
