Bug Found and Fixed in Gemma 4 Chat Template Tool Usage
A bug was discovered in the chat template used by the Gemma 4 model when calling custom tools. The default Gemma chat template failed to correctly process JSON schema structures lacking explicit 'type' fields at the top level (e.g., `anyOf: [$ref, null]`), incorrectly converting useful schema information into empty `type: ""` strings. The author resolved this issue by modifying the Jinja template to preserve critical JSON Schema keywords such as `$ref`, `anyOf`, `oneOf`, and `$defs`.
Key takeaways
Gemma 4's default chat template loses useful information when processing specific JSON schema patterns (e.g., nullable refs).
The issue resided not in the model's reasoning ability, but in the chat template (Jinja) responsible for converting tool parameters into prompts.
The author improved the Jinja template to accurately preserve complex JSON Schema structures like `$ref`, `anyOf`, `oneOf`, and `$defs`.
This fix is a core update enabling Gemma 4 to call custom tools perfectly.
