My Wiki.js site needs help with some bugs

I've created a wiki.js page and have dozens of pages and data written. My site is on hosted on DigitalOcean.

I recently added AWS for global searching, but it is not working and giving an error code. I followed the guide, but something must not be right.

I just added the SSL, but now when I go to save a page I get the following error messages (see pics).

Advice is welcome. I'd like to be able to solve this myself; however, I am a little busy at the moment and would like these issues off my plate.
