JSON parse exception prevents editing or deleting of instructable

Try creating an instructable with the text below in the description. When you save it, a JSON parse error pops up. The same exception will pop up each time you go to edit the instructable, preventing you from reaching the edit page or ever deleting it. You apparently need to sanitize your input a bit more.

SET count=0
FOR /f %%a IN ('dir /b *.jpg') DO (
set /a xOffset = !count!*2
set /a xSize = 1098+!count!*6
set /a yOffset = !count!*1
set /a ySize = 732+!count!*4
"C:\Program Files\ImageMagick-6.7.3-Q16\convert.exe" %%a[!xSize!x!ySize!+!xOffset!x+!yOffset!] pan-%%a
set /a count=count+1

The exact exception is: "There's been a problem updating your Instructable
[object Object]
SyntaxError: JSON.parse: bad escaped character"

Thank you! Passing this on to people who might be able to read what that says.

May I ask what that code means and why you're putting it into the instructable?

Sure. I was giving an example of how to write a script that batch edits photos for this instructable: https://www.instructables.com/id/Pan-Zoom-time-lapse-photography-on-the-cheap/

To work around the problem, I've attached the script to the instructable as a txt file instead.
