Creating Headline Returns "Wrong number of arguments: (0 . 0), 2

[dleszcynski]

Org-brain has been working fine until this morning. I tried creating a headline and I get the message:
org-brain-get-tags: Wrong number of arguments: (0 . 0), 2
I've run org-brain-update-id-locations and am still getting the same thing. I have just begun the process of creating a custom init.el and so emacs is almost completely plain, out of the box. I haven't customized org-brain at all and have been using it fine until now. I have not been able to find anything specific to org-brain and this error online.

That's strange. Try running M-x toggle-debug-on-error and post the log here. Also see what M-x org-version says.

I'm relatively new to emacs, so this is probably my fault, but thanks for your help!

org-brain requires org-mode version 9.2. I think org-get-tags was changed in version 9.2, so my guess is that is the reason it doesn't work.

We've all been new, no worries! Here's instructions on installing new org-mode versions: https://orgmode.org/elpa.html

I knew that it was probably something simple. Thank you a million! I'm loving org-brain.
