run the vosk on worker task in nodejs

Hi,

I succeeded in running the nodejs simple example using FFmpeg. Now I would like to
using Bree scheduler to execute the above example as a worker task. But whenever It comes to the below part the process automatically killed. Pls, help to show me what is the problem? and how can I fix it? thank you very much.

const libvosk = ffi.Library(soname, {
'vosk_set_log_level': ['void', ['int']],
'vosk_model_new': [vosk_model_ptr, ['string']],
'vosk_model_free': ['void', [vosk_model_ptr]],
'vosk_spk_model_new': [vosk_spk_model_ptr, ['string']],
'vosk_spk_model_free': ['void', [vosk_spk_model_ptr]],
'vosk_recognizer_new': [vosk_recognizer_ptr, [vosk_model_ptr, 'float']],
'vosk_recognizer_new_spk': [vosk_recognizer_ptr, [vosk_model_ptr, vosk_spk_model_ptr, 'float']],
'vosk_recognizer_new_grm': [vosk_recognizer_ptr, [vosk_model_ptr, 'float', 'string']],
'vosk_recognizer_free': ['void', [vosk_recognizer_ptr]],
'vosk_recognizer_accept_waveform': ['bool', [vosk_recognizer_ptr, 'pointer', 'int']],
'vosk_recognizer_result': ['string', [vosk_recognizer_ptr]],
'vosk_recognizer_final_result': ['string', [vosk_recognizer_ptr]],
'vosk_recognizer_partial_result': ['string', [vosk_recognizer_ptr]],
});
