Recurring error when looking out to use my very own color mod

I aesthetic made a mod to interchange the player colours through altering values in the “spritecolors” file. It no doubt works stunning when I change the file manually. I birth a game and my recent colours are all there.

Then I attempted to execute a mod (dataset) of it. But when I strive to execute a mod of it in the local mod folder (mods/local/mymodname/sources/_common/dat/spritecolors) I procure this error message when beginning a game with my dataset.

I mustn’t own any thought what this “AoE2DE.gvp” file is, for it doesn't exist in the game folder at all. Any ideas on what went inferior? Would possibly presumably well be very grateful for any help!
