For a couple of days, I have been having some errors while setting up Yoast and running the SEO Data Optimization. Even ChatGPT couldn't help!

Digged deeper, checked the Chrome Deev Tools Network tab, and found that it was a not found error. It could not resolve a 'prepare' route.

Decided to set up my WP permalinks to Post name and that solved the issue!

I hope this helps someone out there facing same issue.
