Fatal error 'Unable to determine class for field type 'metatag_computed'...' after update to 1.26

Apologies, I should have searched for the error instead of just checking recent issues. I see it is related to a patch in 📌 Support JSON API, REST, GraphQL and custom normalizations via new computed field Fixed which was fixed. I did remove this patch in a previous update, and this error only came up today when updating to 1.26. So I'm a little confused, but probably something I need to fix on my end.

My bad was assuming the fix was applied to the 1.x branch. Not sure why I didn't see an error sooner, but fortunately this all happened locally. Ended up rolling back to 1.23 and reapplying the patch in #2945017: Warning on Message settings page → until I am able to update to 2.x.

Sorry for the noise! Might as well close this.

Thanks for reporting back to confirm the bug was related to the patch from #2945817 not being applied.
