Blog posts not loading in new theme, server error 422

[PeacefieldTitan]

Hey there!

I am having an issue with my new theme (impulse) with my blog post not appearing. The blog is there and links to the individual blog post are present. When I click on the thumbnail to read the post it goes to a blank page. i click inspect on the blank page and an error message appears in the script. if I preview my old theme, the blog posts appear just fine. It's not the setting to "visible" issue others have had. Clicking "inspect" on blank page where the post should be reveals error message...failed to load resource, server error 422.
