Interaction has already been acknowledged

[ctrl-Felix]

I have a button in a view created with this:

view = discord.ui.View()
item = discord.ui.Button(style=discord.ButtonStyle.blurple, label="Click", custom_id=f"id_{str(id)}")
view.add_item(item=item)

I then handle the interaction with:

@bot.listen()
async def on_interaction(interaction):
    await interaction.response.defer(ephemeral=True, thinking=True)
    if interaction.user.bot:
        return
    ...

But I keep getting this on new views:

  File "/root/discordtipbotcode/venv/lib/python3.9/site-packages/discord/client.py", line 384, in _run_event
    await coro(*args, **kwargs)
  File "/root/discordtipbotcode/bot/modules/wallet.py", line 408, in on_interaction
    await interaction.response.defer(ephemeral=True, thinking=True)
  File "/root/discordtipbotcode/venv/lib/python3.9/site-packages/discord/interactions.py", line 486, in defer
    await adapter.create_interaction_response(parent.id, parent.token, session=parent._session, params=params)
  File "/root/discordtipbotcode/venv/lib/python3.9/site-packages/discord/webhook/async_.py", line 194, in request
    raise HTTPException(response, data)
discord.errors.HTTPException: 400 Bad Request (error code: 40060): Interaction has already been acknowledged.
Ignoring exception in on_interaction
Traceback (most recent call last):

    raise HTTPException(response, data)
discord.errors.HTTPException: 400 Bad Request (error code: 40060): Interaction has already been acknowledged.

Once I restart the bot the older views work. But if I create a new one it's not working...
The error already appears multiple times on the same instance

Addition:
If I add a asyncio.sleep(2) before .defer() I get discord.errors.InteractionResponded: This interaction has already been responded to before

There are multiple issues here.

1. You are setting a custom_id explicitly, which might have a chance of conflict unless you're going out of way to ensure they are unique.
2. You are responding to every interaction the bot sees instantly with a defer. Any response you do after that is bound to fail.

You should use the callback attached to a button instead of using on_interaction, that's what they're there for.

They are definetly unique

Shouldn't interaction.followup.send work?

Is there an example for the callback somewhere?

A followup isn't a response.

There are examples in the repository under the views folder.
