Bad file descriptor - error with sed

I'm learning SED command. And while doing that i got to this place where i'm taking a copy of my existing file. The code i used is -
Code:
sed -n '/Storm/ w Storm.txt' books.txt

As expected, the file 'books.txt' is read , and lines with 'Storm' is put in to the new file 'Storm.txt'. However, it also throws the below error -
sed: read error: Bad file descriptor

Can someone help me understand why is it happening.

Your sed command is a bit unusual but should work as intended.
What is your OS?
Code:
uname

The normal working with sed is with stdout. Of course it then needs an invoking shell that redirects its stdout to the output file:
Code:
sed -n '/Storm/ p' books.txt > Storm.txt

As I'm learning these things now, i'm practicing in 'https://vfsync.org/vm.html?login=1'.
This gives an online terminal to practice.
It's 'Linux'.

I tried your command, and produces same result as i got early, however without the error message.

Looks more like a deficiency of that web site, as I can replicate the error with the usually OK command given in post#1.
