Thanks for answering me,
i don't get error, but the output file doesn't show me the documents ID.
(50 topics set)
{0:0.002547369011977743,1:0.00233198734746577,2:0.0027053304459988474,........,46:0.002681078237741154,47:0.0022995728183704102,48:0.0023898609263648157,49:0.0025577382030260733}
{0:0.0172651678913815,1:0.021788291490618214,2:0.01963763437656911,3:0.016126441969287045,4:0.017164489962241965,..........,46:0.02035978725089203,47:0.014235145717055388,48:0.015352609835937277,49:0.015562410201527429}
etc.
Which document corresponds to each of these rows?
The console log messages are:
