First off, not entirely sure if this should be reported to this project or the wielded_light project.
I had placed an item frame (itemframes https://content.minetest.net/packages/TenPlus1/itemframes/ ) and then placed a lighted helmet made from a bronze helmet (3d_armor) into the item frame and the server crashed. I did this twice with same result.
I'm not able to reproduce the problem. But it does look like you are using a different version of wielded_light than I am. Have you checked to see if you can update wielded_light?
