Why am i getting this discordAPIerror - node.js

Question

so i was trying to make a discord bot and it is giving me this error:
DiscordAPIError[50035]: Invalid Form Body
0.name[BASE_TYPE_REQUIRED]: This field is required
at SequentialHandler.runRequest (C:\Users\Admin\Desktop\bot\node_modules#discordjs\rest\dist\lib\handlers\SequentialHandler.cjs:287:15)

at async Client.client.handleCommands (C:\Users\Admin\Desktop\bot\src\functions\handlers\handleCommands.js:28:9) {
rawError: {
code: 50035,
errors: { '0': [Object] },
message: 'Invalid Form Body'
},
code: 50035,
status: 400,
method: 'PUT',
url: 'https://discord.com/api/v9/applications/1009341661572243516/guilds/688019305299706004/commands',
requestBody: { files: undefined, json: [ [Object], [Object] ] }
}
the code is as follows:
const { Routes } = require('discord-api-types/v9');
const fs = require('fs');
module.exports = (client) => {
client.handleCommands = async () => {
const commandFolders = fs.readdirSync('./src/commands');
for (const folder of commandFolders) {
const commandFiles = fs
.readdirSync(`./src/commands/${folder}`)
.filter((file) => file.endsWith('.js'));
const { commands, commandArray } = client;
for (const file of commandFiles) {
const command = require(`../../commands/${folder}/${file}`);
client.commands.set(command.data.name, command);
commandArray.push(command, command.data.toJSON());
}
}
const clientId = '1009341661572243516';
const guildId = '688019305299706004';
const rest = new REST({ version: '9' }).setToken(process.env.token);
try {
console.log('Started refreshing application (/) commands.');
await rest.put(Routes.applicationGuildCommands(clientId, guildId), {
body: client.commandArray,
});
console.log('Successfully reloaded application(/) commands.');
} catch (error) {
console.error(error);
}
};
};
command file:
module.exports = {
data: new SlashCommandBuilder()
.setName("ping")
.setDescription("Returns a ping"),
async execute(interaction, client) {
const message = await interaction.deferReply({
fetchReply: true,
});
const newMessage = `API Latency: ${client.ws.ping}\n Client Ping: ${
message.createdTimestamp - interaction.createdTimestamp
}`;
await interaction.reply({
content: newMessage,
});
},
};

The error is from your commandArray, you are pushing 2 elements but as you can see in the documentation (https://discordjs.guide/interactions/slash-commands.html#guild-commands ), we just need to pass command.data.toJSON() and not command, command.data.toJSON(). I had the same issue and it worked for me.
Here is the right formated code
const { Routes } = require('discord-api-types/v9');
const fs = require('fs');
module.exports = (client) => {
client.handleCommands = async () => {
const commandFolders = fs.readdirSync('./src/commands');
for (const folder of commandFolders) {
const commandFiles = fs
.readdirSync(`./src/commands/${folder}`)
.filter((file) => file.endsWith('.js'));
const { commands, commandArray } = client;
for (const file of commandFiles) {
const command = require(`../../commands/${folder}/${file}`);
client.commands.set(command.data.name, command);
commandArray.push(command.data.toJSON());
}
}
const clientId = '1009341661572243516';
const guildId = '688019305299706004';
const rest = new REST({ version: '9' }).setToken(process.env.token);
try {
console.log('Started refreshing application (/) commands.');
await rest.put(Routes.applicationGuildCommands(clientId, guildId), {
body: client.commandArray,
});
console.log('Successfully reloaded application(/) commands.');
} catch (error) {
console.error(error);
}
};
};
