wait_for 'reaction_add' check doesn't work

I'm doing a command where you need to confirm something with emojis. I have a wait_for("reaction_add") with a check as a lambda function.

The following code I have is:

try:
    reaction, user = await self.client.wait_for("reaction_add",
    check=lambda react, usr: str(reaction.emoji) == "✅" and usr.id == ctx.author.id, timeout=60)
    print(reaction.emoji)
except asyncio.TimeoutError:
    await confirm_msg.edit(content="This message has timed out!", embed=None)

But it doesn't print out the reaction emoji. Without the check the code works fine, so it has to do with the check. How could I fix it?

Thanks!

You can try this, without the lambda function:

@client.event
async def on_raw_reaction_add(payload):
  reaction = str(payload.emoji)
  if reaction == "✅" and usr.id == ctx.author.id:
     print('do something')
  else:
     print('something else')

A lambda function is esentially the same as a normal function.

Your lambda:

lambda react, usr: str(reaction.emoji) == "✅" and usr.id == ctx.author.id

Would be equal to defining the following function:

# Here we are within the wait_for(reaction_add)
def f(react, usr):
    return str(reaction.emoji) == "✅" and user.id == ctx.author.id
# Rest of the code

The problem is that the reaction_add does not have react or usr defined. The way to solve your code would be something like this:

reaction, user = await self.client.wait_for("reaction_add", check=lambda reaction,
user: str(reaction.emoji) == "✅" and user.id == ctx.author.id, timeout=60)
