Member.kick and member.ban not working

[advaitvariyar]

This is the code for my kick command in my discord bot:

@client.command(aliases=['k'])
@commands.has_permissions(kick_members = True)
async def kick(ctx, member : discord.Member, *, reason = "Reason not provided"):
    serverName = ctx.message.guild.name
    await member.send("You have been kicked from the " + serverName + ". Reason: " + reason)
    await member.kick(reason=reason)
    await ctx.send("User has been kicked")

However, when I call this command I get no output. I tried print debugging the code and it always stops at the line await member.kick(reason=reason). This is the exception I get:

>> Traceback (most recent call last):
>> File "/app/.heroku/python/lib/python3.6/site-packages/discord/client.py", line 333, in _run_event
>>     await coro(*args, **kwargs)
>>   File "bot.py", line 41, in on_message
>>     if ":" in msg.content[0] and ":" in msg.content[-1]:
>> IndexError: string index out of range

Could someone help me out to fix this problem?

Thanks!

the error is nothing to do with the command its coming from your on_message event, it seems your message's content is empty.
