I had the same error 401
For me I solved it the following:
Facebook has now the option, facebook.com – Account settings, to change to the new Facebook scheme including a dark modus. When doing that Nextscript posting error occurs.
When switching Facebook back to the classic mode (white/blue) mode, postings are working.
I have reported this bug via a ticket. No response received so far.
