I saw that https://mods.factorio.com/mod/miniloader/discussion/620310a56e7833117189b7e9 is marked as fixed, but on 1.15.2 I still get the following error:

The mod Miniloader (1.15.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event miniloader::on_robot_built_entity (ID 14)
miniloader/lualib/util.lua:404: bad argument #1 of 2 to 'pairs' (table expected, got nil)
stack traceback:

The crash happens when pasting a miniloader even without a circuit connection.

Can you try v1.15.3?

Great! The action I tried that crashed before seems to work now. Thanks for the mod and the quick fix!
