How to fix this error about PetActionButton's Text

[NottheSin]

I'm using this Lua to replace the hotkey text.
But there is a error in DF.
Can anyone help me to fix it?

local gsub = string.gsub
 
local function HotkeyReplace(button)
    local text = button.HotKey and button.HotKey:GetText()
    if not text then return end
 
    text = gsub(text, '(s%-)', 's')
    text = gsub(text, '(a%-)', 'a')
    text = gsub(text, '(c%-)', 'c')
    text = gsub(text, '(st%-)', 'c') -- german control 'Steuerung'
 
    for i = 1, 30 do
        text = gsub(text, _G['KEY_BUTTON'..i], 'M'..i)
    end
 
    for i = 1, 9 do
        text = gsub(text, _G['KEY_NUMPAD'..i], 'N'..i)
    end
 
    text = gsub(text, CAPSLOCK_KEY_TEXT, 'CK')
    text = gsub(text, KEY_NUMPADMULTIPLY, '*')
    text = gsub(text, KEY_NUMPADDIVIDE, '/')
    text = gsub(text, KEY_NUMPADPLUS, '+')
    text = gsub(text, KEY_NUMPADMINUS, '-')
    text = gsub(text, KEY_MOUSEWHEELUP, 'MU')
    text = gsub(text, KEY_MOUSEWHEELDOWN, 'MD')
    text = gsub(text, KEY_NUMLOCK, 'NuL')
    text = gsub(text, KEY_PAGEUP, 'PU')
    text = gsub(text, KEY_PAGEDOWN, 'PD')
    text = gsub(text, KEY_SPACE, '_')
    text = gsub(text, KEY_INSERT, 'Ins')
    text = gsub(text, KEY_HOME, 'Hm')
    text = gsub(text, KEY_DELETE, 'Del')
 
    button.HotKey:SetText(text)
end
 
local lgr, lgg, lgb = LIGHTGRAY_FONT_COLOR:GetRGB()
local function SetButtonFont(button)
    if button.HotKey then
        button.HotKey:SetFont(button.HotKey:GetFont(), 12, 'OUTLINE')
        -- update hotkey color
        hooksecurefunc(button.HotKey, 'SetVertexColor', function(self, r, g, b)
            if r == lgr and g == lgg and b == lgb then
                self:SetVertexColor(1, 1, 1)
            end
        end)
    end
    if button.Name then
        button.Name:SetFont(button.Name:GetFont(), 12, 'OUTLINE')
    end
end
 
local frame = CreateFrame('Frame')
frame:RegisterEvent('PLAYER_LOGIN')
frame:SetScript('OnEvent', function()
    frame:UnregisterEvent('PLAYER_LOGIN')
 
    -- process old buttons
    -- action bar
    for _, button in ipairs(ActionBarButtonEventsFrame.frames) do
        SetButtonFont(button)
        HotkeyReplace(button)
        hooksecurefunc(button, 'UpdateHotkeys', HotkeyReplace)
    end
    -- pet action bar
    for i = 1, 10 do
        local button = _G['PetActionButton' .. i]
        SetButtonFont(button)
        button.HotKey:SetPoint('TOPRIGHT', -1, -4)
        HotkeyReplace(button)
    end
 
    -- action bar
    hooksecurefunc(ActionBarButtonEventsFrame, 'RegisterFrame', function(_, button)
        SetButtonFont(button)
        hooksecurefunc(button, 'UpdateHotkeys', HotkeyReplace)
    end)
    -- pet action bar
    hooksecurefunc('PetActionButton_SetHotkeys', HotkeyReplace)
end)

The error:

1x Interface/AddOns/HotkeyFont/HotkeyFont.lua:80: hooksecurefunc(): PetActionButton_SetHotkeys is not a function
[string "=[C]"]: in function `hooksecurefunc'
[string "@Interface/AddOns/HotkeyFont/HotkeyFont.lua"]:80: in function <Interface/AddOns/HotkeyFont/HotkeyFont.lua:56>

It would be something like this

for _, btn in pairs(PetActionBar.actionButtons) do
    hooksecurefunc(btn, "SetHotkeys", HotkeyReplace)
end
