Looks like this is thrown from a fork of hydrogen which is unmaintained and might not be compatible with your version of atom. You can install hydrogen by running: apm uninstall greyatom-hydrogen and apm install hydrogen from your command line.

Thanks Ben! I will try your suggestion on a fresh install of Atom and let you know if it worked. Thanks again for taken time to analyze this issue and respond.

Hello Ben, just wanted to update you that after doing a fresh install and only installing the hydrogen package has fixed the issue. As per your suggestion, it worked. Thanks a lot!

I am having this issue with a freshly installed version of Pulsar. I can execute rows if I highlight them, but if I execute the "Run and Move Down" command while the cursor is at the end of the line.

I'm having the same issue with a fresh Pulsar install - running highlighted rows works fine, but executing row-by-row throws the same error.
