Cannot register slash commands discord.js v13

Every time I start registering my application commands, I get this error:

<rejected> DiscordAPIError[50035]: Invalid Form Body
0[DICT_TYPE_CONVERT]: Only dictionaries may be used in a DictTyp

<rejected> DiscordAPIError[50035]: Invalid Form Body

<rejected> DiscordAPIError[50035]: Invalid Form Body

And they are not registered after a few minutes.
