DrpInv Error Help

I have been having trouble with a DrpInv error. It seems to be happening to only me and I, and the server owner, cannot find out why it is happening or how to fix it.
Here is the error outputted to my console after I open my inventory and it kicks me for too many lua errors:

[ERROR] addons/derpinv/lua/autorun/client/cl_drpinv.lua:178: attempt to index local ‘info’ (a nil value)

  1. unknown - addons/derpinv/lua/autorun/client/cl_drpinv.lua:178
  2. unknown - lua/includes/modules/concommand.lua:69

If it helps, I can get the file contents from the server owner, but I will only do so if needed.
Thanks for helping!

And just a little off topic, but I can’t seem to be able to search anywhere on the website, it tells me I have no permission to do so… Can anyone fix that? Sorry for asking that here.

We need the lua code from line 178 (=

Sorry for the wait, the server owner went offline.
Here is the whole cl_drpinv.lua file.

Hope this helps.
