DiscordJS v14 invalid form body

I have been trying to make a slash command with subcommand that sends message to specified channel.
When i try to deploy it, i get:

DiscordAPIError[50035]: Invalid Form Body
options[1][APPLICATION_COMMAND_OPTIONS_TYPE_INVALID]: Sub-command and sub-command group option types are mutually exclusive to all other types

}

My code:

const { SlashCommandBuilder } = require('discord.js');

const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({ intents: [GatewayIntentBits.Guilds] });

module.exports = {
    data: new SlashCommandBuilder()
        .setName('say')
        .setDescription('Make bot say anything the executor wants')
        .addSubcommand(subcommand =>
            subcommand
                .setName('channel')
                .setDescription('Says ')
             .addChannelOption(option =>
                  option
                    .setName('target_channel')
                    .setDescription('Channel to send message in.')
                    .setRequired(true)))
              .addStringOption(option =>
                option
                    .setName('text')
                    .setDescription("Message to be sent in specified channel")
                    .setRequired(true)),
    async execute(interaction) {
        const channel = interaction.options.getChannel('target_channel');
        const text = interaction.options.getString('text');

        client.channels.cache.get(channel).send(text);
    },
};

I have no clue about it. I didn’t find anything about it anywhere. I expected it to deploy the commands via node deploy-commands.js but it resulted in error above.

>Solution :

The error is emitted when you attempt to add an option to a command which also has a subcommand. To illustrate this better I’ve create an ascii table, note how channel and text options are on the same level, which would result in an error.

say
 |- channel: SUB_COMMAND
 |   |- name: STRING
 |   |- target_channel: TEXTCHANNEL
 |- text: STRING
 |   |- option: STRING

If I’ve interpreted your code correctly you may want to add the string option to the subcommand, as so:

data: new SlashCommandBuilder()
    .setName('say')
    .setDescription('Make bot say anything the executor wants')
    .addSubcommand(subcommand =>
        subcommand
            .setName('channel')
            .setDescription('Says ')
            .addStringOption(option =>
                option
                    .setName('text')
                    .setDescription("Message to be sent in specified channel")
                    .setRequired(true)
            )
            .addChannelOption(option =>
                option
                    .setName('target_channel')
                    .setDescription('Channel to send message in.')
                    .setRequired(true)
            )
    )
