Discord.js error '.addChoice' is not a function - discord.js

Question

i have some Problems with my Code that somehow none of my friends have ...
Some Code to see:
module.exports = {
data: new SlashCommandBuilder()
.setName('equipment')
.setDescription('Gives you Information about specific Equipments')
.addStringOption(option =>
option.setName('type')
.setDescription('Specify the Equipment')
.setRequired(true)
.addChoice('Flashlight', 'flashlight')
),
...
The Code is Cut here because its not necesery for it above to work.
My Error Code:
PS C:\Users\enric\Desktop\Ghosty Phasmo Help> node .
C:\Users\enric\Desktop\Ghosty Phasmo Help\commands\phasmo\equipment.js:15
.addChoice('Flashlight', 'flashlight')
^

Somehow my Discord.js thinks that im using a Function. I copied the Code from other friends where this completely work. but somehow the same Error message appears.

.addChoice() is outdated. Now, there is only .addChoices() (with an s)
.addStringOption(option =>
option.setName('type')
.setDescription('Specify the Equipment')
.setRequired(true)
.addChoices({
name: 'Flashlight',
value: 'flashlight'
})
)
