Description

A valid model returns an error error running tests due to rpc error: code = Code(2056) desc = the definition of relation 'can_purchase' in object type 'card' is invalid: no entrypoints defined

The DSL seems to parse correctly (CLI transforms it and VS Code shows no validation errors), but the server still returns an error.

Expectation

Tests run successfully on this model.

Reproduction

Run > fga model test --tests stripe.fga.yaml in console
