API returns empty intents and entities for exact training matches

[kuzicki]

I recently created a new Wit.ai app and trained it with around 30 utterances containing varied structures and up to 3 custom/built-in entities (e.g., institution, degree, wit$datetime). The Wit.ai console indicates that the model is fully trained.
However, when I query the API using curl or the official Python wit package, the response returns completely empty intents and entities arrays. This happens even when I send the exact same strings that are validated in my training data.

Steps to Reproduce

1. Create a Wit.ai app set to Russian language.
2. Add training utterances to an intent (e.g., add_education).

• Example trained utterance: "Добавь, что я учился в МГЛУ"
• Mapped entities: institution -> "МГЛУ"

3. Wait for the Wit.ai console to indicate that training is complete.
4. Make an API call using curl or the Python lib with the exact training text
