Same message error, in my case i see this in JS Console:
indexation-1550.js:1 POST https://www.domain.com/wp-json/yoast/v1/link-indexing/posts 500
What can i do? i already do all steps with yoast helper, i reset indexation, even i follow steps with WP Cli, with command wp yoat indes, the process finish correctly, but the table wo_yoast_links doesnt have much information. By the way, i have more than 60K posts.
