Fix AssertionError

✅ Solution

AssertionError in vllm usually arises from unexpected or invalid states during execution, particularly when assumptions within the code are violated, as seen when `max_num_scheduled_tokens` is negative or when data types are incompatible. To fix this, carefully examine the error message and traceback to identify the violated assertion and the specific condition that triggered it; then, add input validation or adjust data types to ensure the asserted condition always holds true before proceeding with execution.
