How To Fix ?

 

[WibbenZ]

Are you other npc files working? In that case post npc/scripts/food.lua otherwise replace your npc/lib/... files with those from the tfs version you are using.

This Is My Scripts Of Npc

You should never do that, either upload all of the files or none.
Its VERY rare that they only change one thing when updating stuff, so what you would do now is probbly give him another error while maybe fixing the old one.

yea but who knows haha maybe he deleted the file by accident

tell us which tfs are you using

 

[WibbenZ]

Just that you have to ask in that case what tfs he is using is another thing, by you just uploading your script can cause other bugs, tell him where he can find the older tfs revs and how to download them.

 

[Limos]

It means you use a different npc lib folder that was not ment for your server, probable because you used a different datapack.
