Can't use await

Question

I'm new to coding Discord bots in Python with the Nextcord library.

I ran into an issue with creating a transcript for a ticket.

The interaction to close the ticket failed due to what Python thinks is an issue.

Here is what my terminal said was the issue:

line 52, in close_ticket messages = await interaction.channel.history(limit=None, oldest_first=True).flatten

TypeError: object method can't be used in 'await' expression Here is my code:

@nextcord.ui.button(
        label="Close Ticket", style=nextcord.ButtonStyle.red, custom_id="ticket_settings:red"
    )
    async def close_ticket(self, button:nextcord.ui.Button, interaction: nextcord.Interaction):
        messages = await interaction.channel.history(limit=None, oldest_first=True).flatten
        contents = [message.content for message in messages]
        final = ""
        for msg in contents:
            msg = msg + "\n"
            fianl = final + msg
        with open('transcript.txt', 'w') as f:
            f.write(final)
        await interaction.response.send_message("Ticket is being closed.")
        await interaction.channel.delete()
        await interaction.user.send(f"Ticket closed in {interaction.channel.mention}. Here is the transcript.", file=nextcord.File(r'transcript.txt'))
        os.remove("transcript.txt")

Answer 1

flatten is a method (see this), you need to call it to use it in an await expression by adding () at the end.

To fix your issue, change this line:

messages = await interaction.channel.history(limit=None, oldest_first=True).flatten

Into this line:

messages = await interaction.channel.history(limit=None, oldest_first=True).flatten()

Off topic to your issue, but there's also a small typo in your code:

fianl = final + msg
