I am following the snippet provided by John on Nov 2016 and I can get an error log from within the final ‘if’ before returning “This Value is not Unique”. However,
1. that error message does not show up on the custom post page while I am editing it.
2. the post gets saved

Can someone help?

I’ve implemented the function using the ‘snippets’ plugin and my backend editor is gutenberg

Cheers,
Karthik
