Discord JS: Cannot find Module

I’m working on implementing slash commands to my bot. For that I made a deploy-commands.js which is located in ./src/deploy-commands.js. My commands are located in ./src/commands/. At the moment my only command is a simple ping.js. With the following code I’m trying to read the commands in my commands folder and push them into an array.

require("dotenv").config()
const fs = require("fs")
const { REST } = require("@discordjs/rest")
const { Routes } = require('discord-api-types/v9')
const commands = []

const CommandFiles = fs.readdirSync("./src/commands").filter(file => file.endsWith(".js"))

CommandFiles.forEach(commandFile => {
    const command = require(`.commands/${commandFile}`)
    commands.push(command.data.toJSON())
})


const restClient = new REST({version: "9"}).setToken(process.env.DISCORD_BOT_TOKEN)



restClient.put(Routes.applicationGuildCommands(process.env.DISCORD_APPLICATION_ID, process.env.DISCORD_GUILD_ID),
{body: commands})
.then(() => console.log("Commands wurden geladen!"))
.catch(console.error)

Also I created a script in my package.json to easily run the deploy-commands.js file. Now when I run my script via npm run deployCommands I get the following error:

Error: Cannot find module '.commands/ping.js'
