Drupal 8.x

I want to display Field "field_summary" and "field_tags" of a node in html.html.twig (without using a module for that) as metatags. I was already able to get "field_summary" value in html.html.twig with this code:

Hi,

I need to include in my site a birthday date field. The issue is that not all the content has a standard date (Year, Month and Day)... some field can have "Partial Dates" such as just the Year; Year and Month; Year, Month and a range of days; or a century.

This was done by the Partial Date module in version 7, but it is not currently updated to version 8.

I'm an amateur, not a professional developer, but I've been using Drupal for a number of years and have built a number of D7 and D8 sites, but this is brand new for me and I'm baffled. I'm not even sure this is a drupal problem as opposed to something related to my host.

Created new MySQL database, uploaded tar.gz of 8.8.6, unpacked it, navigated with my browser to install and did the install process as usual. After the last step in that process (setting basic site configureation with site name, email. admin name and password) it get the following message:

Hi everyone.  I'm new here and have a question for my drupal 8 website.  I'm trying to embed some code and am having a little trouble...
