Please report this error to the mod author.

Error while running event cargo-bay-inserters::on_tick (ID 0)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
[C]: in function 'index'
__cargo-bay-inserters/control.lua:164: in function 'update_proxies_for_surface'
cargo-bay-inserters/control.lua:190: in function <cargo-bay-inserters/control.lua:187>

with quality

the line numbers confused me for a bit but i've appeared to have fixed it, try 1.0.1.

Thanks

Same again

could you send me a world where placing one down immediately causes this crash?

you able to VC to show how it happen?

actually looking at the error a third time might give me a clue as to what happened, did you place/upgrade cargo bay, or did you upgrade a cargo landing pad?

Thanks that fixed it

glad to hear that upgrading cargo landing pads no longer crash for you
