Hi
Yes, I have already reset the indexables using the Yoast Test Helper plugin and completed the SEO data optimization process again.
The error doesn’t happen if I used wp-rollback to go back to 18.2.
Upgrading back to 18.3 it resurfaces. Resetting indexables onces doesn’t fix it. However, after resetting the indexables a few times, it appears to fix it. But after a few posts comes back.
