I can't find what makes the error, does anyone know how to fix it?

I was following a tutorial and did exactly what it showed but it doesn't work and I can't figure out why.

-----------------------------------------------------------------------------------------
--
-- main.lua
--
-----------------------------------------------------------------------------------------

local sheetOptions = {
    width = 512,
    height = 256,
    numFrames = 8
}

local sheet_runningCat = graphics.newImageSheet( "sprites-cat-running.png", sheetOptions )

local sequences_runningCat = {
    {
        name = "normalRun",
        start = 1,
        count = 8,
        time = 800,
        loopCount = 0,
        loopDirection = "forward"
    }
}

local runningCat = display.newSprite( sheet_runningCat, sequences_runningCat )

It creates this error...

main.lua:26: bad argument #1 to 'newSprite' (ImageSheet expected, got nil)
stack traceback:
        [C]: in function 'newSprite'
        main.lua:26 in main chunk
        
Do you want to relaunch the project?

It means that the file "sprites-cat-running.png" was not found in the same directory as this file main.lua so graphics.newImageSheet() returns a nil value, and sheet_runningCat is now nil instead of an ImageSheet object.

To fix this, download the image file from the tutorial and save it in the same directory as main.lua
