Llama Grammar Error

[mariopcorreia]

I was trying to use the grammar_path with the json sample example, and i got this error, for which i could not find any information online:

Exception ignored in: <function LlamaGrammar.del at 0x0000017400035A60>
Traceback (most recent call last):
File "C:\Users\Admin\Desktop\Ubi\sistema-avancado-de-selecao-para-a-gestao-automatizada-de-recursos-humanos.venv\lib\site-packages\llama_cpp\llama_grammar.py", line 50, in del
AttributeError: 'NoneType' object has no attribute 'llama_grammar_free'

This happens right after invoking and completion of a load_qa_chain.
