I am working on a roblox search slash command but it isn't exactly working correctly, I would like some support of revamping these

I want to make a /searchroblox command. Below is what I have

main.py:

from roblox import *
@tree.command(name = "searchroblox", description = "Sends roblox username", guild = discord.Object(id = 1080684956130496542))
async def searchroblox(ctx, *, username: str):
  robloxuser = robloxUser(username)
  embed = discord.Embed(color=0xa3fff7, title=f"Info for {username}")
  embed.add_field(name="Username",value="`" + username + "`")
  embed.add_field(name="Display Name", value="`" + robloxuser.getdn() + "`")
  embed.add_field(name="User ID", value="`" + str(robloxuser.getid()) + "`")
  embed.add_field(name="Description", value= "```" + (robloxuser.getdesc() or "No description") + "```")
  await ctx.response.send_message(embed=embed)
  if isinstance(ctx.channel, discord.DMChannel):
   return

roblox.py:

from ro_py import Client
robloxclient = Client()

class robloxUser:
	def __init__(self, rblox):
		rbloxuser = robloxclient.get_user_by_username(rblox)
	def username(self, rbloxuser):
		self.__user = rbloxuser.name
		
	def display_name(self, rbloxuser):
		self.__dn = rbloxuser.display_name
		
	def userid(self, rbloxuser):
		self.__id = rbloxuser.id
		
	def description(self, rbloxuser):
		self.__description = rbloxuser.description or "No description"

	def getruser(self):
		return self.__user
	def getdn(self):
		return self.__dn
	def getid(self):
		return self.__id
	def getdesc(self):
		return self.__description

After running the code it would show.

main.py:145: RuntimeWarning: coroutine 'Client.get_user_by_username' was never awaited
  robloxuser = robloxUser(username)

    return self.__dn

The above exception was the direct cause of the following exception:

    raise CommandInvokeError(self, e) from e
discord.app_commands.errors.CommandInvokeError: Command 'searchroblox' raised an exception: AttributeError: 'robloxUser' object has no attribute '_robloxUser__dn'

What would I have to do to fix this. I commented all this to avoid problems with the rest of my code by the way.

robloxUser keeps saying it doesn't connect with ro_py file set after I do use it.

Edits: I removed roblox.py:
main.py:

import ro_py
from ro_py import Client
@tree.command(name = "searchroblox", description = "Sends roblox username", guild = discord.Object(id = 1080684956130496542))
async def searchroblox(ctx, *, username: str):
  x = Client()

  robloxuser = await x.get_user_by_username(username)
  embed = discord.Embed(color=0xa3fff7, title=f"Info for {username}")
  embed.add_field(name="Username",value="`" + username + "`")
  embed.add_field(name="Display Name", value="`" + robloxuser.display_name + "`")
  embed.add_field(name="User ID", value="`" + str(robloxuser.id) + "`")
  embed.add_field(name="Description", value= "```" + (robloxuser.description or "No description") + "```")
  await ctx.response.send_message(embed=embed)
  if isinstance(ctx.channel, discord.DMChannel):
   return

This is my new code, below shows what I got, I am commenting it again just in case it crashs my other code.

    raise UserDoesNotExistError

: Command 'searchroblox' raised an exception: UserDoesNotExistError:

The error

RuntimeWarning: Enable tracemalloc to get the object allocation traceback

This warning means that the code was not awaited. The function used is asynchronous meaning that you have to use the await keyword. The await keyword can only be used in asynchronous functions.

You don't need to create an entire roblox.py file

The library does all the work for you. Instead, do the following within your already async function:

robloxuser = await client.get_user_by_username(username)

Then in the embed, you can use the properties of the robloxuser variable.

  embed.add_field(name="User ID", value="`" + str(robloxuser.id) + "`")
  embed.add_field(name="Description", value= "```" + (robloxuser.description or "No description") + "```")

See a nice example here.

Your update

Your error:

: Command 'searchroblox' raised an exception: UserDoesNotExistError:

This just means that the user you inputted does not exist. Use a try except statement to return that to the user who ran the command.
