the code is

f = js2py.eval_js(run_js)
video_url = f()

sometimes it occurred error

i print which run error js code , and create a test python code like only js2py.eval_js(xxxx), it run success.

So, I think the js code is right, but I don't know why full python program run, the same js code will raise execption

I found when run in thread , the code run in concurrent, it will raise error

add time.sleep() to make eval_js() wait a moment, it will run success

i meet it too

During handling of the above exception, another exception occurred: ... raise RuntimeError('No lval found "%s"' % lval) RuntimeError: No lval found "PyJs_LONG_247_"

seems it is not threadsafe?
