Bot treating register-commands.js file like its not there.

This is my index.js

require("dotenv").config();
const { Client, IntentsBitField } = require("discord.js");

const client = new Client({
  intents: [
    IntentsBitField.Flags.Guilds,
    IntentsBitField.Flags.GuildMembers,
    IntentsBitField.Flags.GuildMessages,
    IntentsBitField.Flags.MessageContent,
  ],
});

client.on("ready", (c) => {
  console.log(`${c.user.username} is online.`);
});

client.on("interactionCreate", (interaction) => {
  if (!interaction.isChatInputCommand()) return;

  if (interaction.commandName == "ping") {
    interaction.reply("Pong!");
  }
});

client.login(process.env.TOKEN);

require("dotenv").config();
const { Client, IntentsBitField } = require("discord.js");

const client = new Client({
  intents: [
    IntentsBitField.Flags.Guilds,
    IntentsBitField.Flags.GuildMembers,
    IntentsBitField.Flags.GuildMessages,
    IntentsBitField.Flags.MessageContent,
  ],
});

client.on("ready", (c) => {
  console.log(`${c.user.username} is online.`);
});

client.on("interactionCreate", (interaction) => {
  if (!interaction.isChatInputCommand()) return;

  if (interaction.commandName == "ping") {
    interaction.reply("Pong!");
  }
});

client.login(process.env.TOKEN);

And this is my register-commands.js

require("dotenv").config();
const { REST, Routes } = require("discord.js");

const commands = [
  {
    name: "ping",
    description: "Replies with Pong!",
  },
];

const rest = new REST({ version: "10" }).setToken(process.env.TOKEN);

(async () => {
  try {
    console.log("Started refreshing application (/) commands.");

    await rest.put(Routes.applicationCommands(process.env.CLIENT_ID), {
      body: commands,
    });

    console.log("Successfully reloaded application (/) commands.");
  } catch (error) {
    console.error(error);
  }
})();

require("dotenv").config();
const { REST, Routes } = require("discord.js");

const commands = [
  {
    name: "ping",
    description: "Replies with Pong!",
  },
];

const rest = new REST({ version: "10" }).setToken(process.env.TOKEN);

(async () => {
  try {
    console.log("Started refreshing application (/) commands.");

    await rest.put(Routes.applicationCommands(process.env.CLIENT_ID), {
      body: commands,
    });

    console.log("Successfully reloaded application (/) commands.");
  } catch (error) {
    console.error(error);
  }
})();
