Config error with MMM-TelegramBot - Parenthesized pattern

[djtale]

Hello,

I’m having error when checking my config file :

[07.04.2021 18:28.20.938] [ERROR] Line 115 column 93: Parsing error: Parenthesized pattern

It seems to be caused by the customCommand.
Could someone help me finding out what is wrong in my syntax ?

customCommands: [
{
command: "nextpage",
description: "Passe à la page suivante",
callback: (command, handler) => {
self.sendNotification("PAGE_INCREMENT"),
handler.reply("TEXT", "Voici la page suivante!")
}
},
{
command: "previouspage",
description: "Passe à la page précédente",
callback: (command, handler, self) => {
self.sendNotification("PAGE_DECREMENT")
handler.reply("TEXT", "Voici la page précédente!")
}
},
{
command: "pronote",
description: "Passe à la page PRONOTE",
callback: (command, handler, self) => {
self.sendNotification("PAGE_CHANGED",6)
handler.reply("TEXT", "Voici ProNote!")
}
},
{
command: "pause",
description: "Stop la rotation automatique",
callback: (command, handler, self) => {
self.sendNotification("PAUSE_ROTATION")
handler.reply("TEXT", "OK, rotation arretée")
}
},
{
command: "resume",
description: "Redémarre la rotation automatique",
callback: (command, handler, self) => {
self.sendNotification("RESUME_ROTATION")
handler.reply("TEXT", "OK, rotation démarrée")
}
}
]

Thanks
