Warning & Errors on Google Search Console with field types

Hello
I use 2.3.0 Stb Vertion Joomla 3.9.16 php 7.26

I see this errors many months ago and i wander if any one have the same erros or wornings. I see that all this fields missing from Jem.:

Missing field "offers"

Missing field "image"

Missing field "performer"

Missing field "eventAttendanceMode"

Missing field "eventStatus"

Missing field "description"

Missing field "endDate"

Missing field "location.name"

my site is athens-dayandnight.gr/agenda-events-athens/events

I know, google wants more and more infos by structured data but for the normal user of JEM this is too much. So I think for your extended use you have to insert by yourself.

Yes i know that. Always something want. The problem is that i do not know to do it.

Thank you

When I test your URLsite with
search.google.com/structured-data/testing-tool

I get 0 errors and 6 warnings for each event
warnings mean: "This field is recommended. Please enter a value, if possible!
So if it's not possible, let it!
If you have the possibility to enter via ftp, look into the code e.g. of event detail view:
you will find some itemprop="name" inside of classes e.g.
<dd class="jem-title" itemprop="name">
So you can classify microdatas with the rules of schema.org/Event " You can find the rules there too.

Perhaps you can add some microdata in the same way, e.g. you have big images you could classify like that too.

I am not an expert nor a programmer, but this should work! Perhaps others know it better. Then help or you will be an expert then. Good Luck G
