Description

When tries to get user of message interaction via await ctx.message.interaction.user() it raises an exception

Ignoring exception in Component Callback for message_delete:
Traceback (most recent call last):
  File "bot/venv/Lib/site-packages/interactions/client/client.py", line 1890, in __dispatch_interaction
    response = await callback
               ^^^^^^^^^^^^^^

    await self.call_callback(self.callback, context)

    await self.call_with_binding(callback, context, **context.kwargs)  # type: ignore

AttributeError: 'MessageInteraction' object has no attribute 'get_user'

Changes

• Make MessageInteraction.user as property, not as async function.
• Use self.client.get_user instead of nonexistent self.get_user
