My Fine-Tuned Gemma 4 Loaded Fine, Then Broke on the First Message

A user fine-tuned Gemma 4 E2B, successfully merging the adapter and exporting to .litertlm. Although the model and tokenizer initialized correctly on a phone, the system failed during the first conversation attempt. The runtime encountered a Jinja template error, specifically stating that the map method has no named get. This compatibility issue only surfaces during inference, not during loading, posing a significant risk for developers presenting live demonstrations at events like a hackathon.
