Modding error

[Vulcan]

Sprite outside of
"__F-mod__/resources/technology/icon/icon_tank_tec.png" (at 64, 64, size 0x0 of 0x0

I have been making a tank into the f-mod because it is developed from the turret car in F-mod. What does this error mean?

On the subject of modding gone wrong, I cannot find the problem in my mod for a fusion reactor after getting the error 'Appdata/roaming/factorio/mods/FusionReactor/'prototypes/entity.lua:1: unexpected symbol near '{' '
I would be grateful for any assistance.
