Custom Template - Null value

Fixed in 3.x dev.

Thank you!

However for some my prod sites i cannot currently move to drupal 10.2 hence is it possible to fix it for version 2, or at least provide some guide what needs to be updated and where so I can update it manually in my case?

I've backported this also to 2.x dev. I'm confused as you have submitted several issues with some tagged to 3.x and some to 2.x. Is everything you submitted a 2.x issue? Please tag according to the version you're using so I can help you.

I do have developmnent site with 2.0.1 to reflect my prod enviroment. Hovever with wamp server i used clean version of drupal 10.2.4 so I am also testing version 3.0.0-beta2 and I have updated version in #3.

Will try to download dev version as you suggested and will get back to you, but there is bank holiday due to Easter so will continue next week with testing.

Thank you so much! This issue was mandatory for me, so if it is really fixed it would be a big step for my project.

I can confirm for both - it works as expected. Can be closed or maybe you can back-port also to version 2.0.1 aslo. But 2dev works for me.
