使用asyncio与nextcord时遇‘coroutine 'sleep' was never awaited’错误求助

错误原因很明确：asyncio.sleep()是异步协程函数，调用时必须用await关键字等待它执行完毕，否则Python会判定这个协程未被处理，抛出你看到的错误。

直接修改代码中的这一行：
将

asyncio.sleep(3)

替换为

await asyncio.sleep(3)

修改后的完整代码：

embed=nextcord.Embed(title=catName, url=catLink, color=0xcc7314)
embed.set_image(url=catURL)
embed.set_footer(text=f"Cat image posted on r/{catSub} by {catPoster}")
finding=nextcord.Embed(description=f"<a:loading:1018351524394569752> Finding `cat` image", color=0xcc7314)
loading = await ctx.reply(embed=finding, allowed_mentions=pingManager)
await asyncio.sleep(3)
await loading.edit(embed=embed)
