How do I set custom Title and Description for 404 template

[anstrx]

Question

I tried {% do seomatic.meta.seoTitle('some error title') %} in my 404.twig file in the head section but the global seomatic title still shows up in the rendered 404 page. How do I override this?

Additional context

Using latest version of Craft 3.x

By default, SEOmatic does not render any metadata for 400-class responses. This is because the metadata is largely for bots, which don't index 404 pages at all.

Probably you should just put the <title> in there yourself as you see fit.
