How to check if a specific document exists in PyMongo?

Question

Python

Is there any way to check a specific document in PyMongo? Tried like this:

@client.command(name='bio')
async def bio(ctx):
    if collection.find_one(ctx.author.id)["bio"] is None:
        emb = discord.Embed(title=f"Биография **{ctx.author.name}**", description="```Нету биографии```",
                            colour=discord.Colour.blue())
        await ctx.send(embed=emb)
    else:
        emb = discord.Embed(title=f"Биография **{ctx.author.name}**", description=collection.find_one(ctx.author.id)["bio"],
                            colour=discord.Colour.blue())
        await ctx.send(embed=emb)

But got this error:

if collection.find_one(ctx.author.id)["bio"] is None:
TypeError: 'NoneType' object is not subscriptable
