code causing the issue:

(async () => {
      for (const file of commandFiles) {
        const command = await import(`./${file}`);
        text += `p/${command.default.name} - ${command.default.description} - command arguments: ${command.default.arguments}\n \n`;
        console.log(typeof command.default.name);
      }
    })();

(async () => {
      for (const file of commandFiles) {
        const command = await import(`./${file}`);
        text += `p/${command.default.name} - ${command.default.description} - command arguments: ${command.default.arguments}\n \n`;
        console.log(typeof command.default.name);
      }
    })();

at EmbedBuilder.setDescription given: '',

sounds like you passed an empty string to setDescription

ayeuhugyu•9mo ago

yeah but im pretty darn sure the string isn't empty

text += `p/${command.default.name} - ${command.default.description} - command arguments: ${command.default.arguments}\n \n`;

text += `p/${command.default.name} - ${command.default.description} - command arguments: ${command.default.arguments}\n \n`;

yknow

which is happening asynchronously, resulting in setDescription being called before anything is added to text
