discord.errors.HTTPException: 400 Bad Request (error code: 50006): Cannot send an empty message when creating embed in discord

Question

Im trying to post an embed in the channel where I post {PREFIX} help as a help embed and here is my code

@bot.event
async def on_message(message):

    if message.content == f"{PREFIX} help":
        if message.author != bot.user:
            return
        embedVar = discord.Embed(title="BlackDC", url="https://github.com/DrkTheDon/BlackDC",description="BlackDC cmds", color=0x00ff00)
        embedVar.add_field(name="Help", value="hi", inline=False)
        embedVar.add_field(name="Test", value="hi2", inline=False)
        await message.channel.send(embed=embedVar)
        await message.channel.send(embed=embedVar)

        print(f"{Fore.BLUE}{curtime} {Fore.YELLOW}[*] {Fore.LIGHTWHITE_EX}Sent {Fore.RED}Help Commands{Fore.LIGHTWHITE_EX} in {Fore.YELLOW}#{message.channel} ")
    elif message.content == f"{PREFIX}":
        await message.channel.send(f"{message.author.mention} This bot is under development!") 

But then I get this ERROR:
