Code

        except Exception as e:
            print(sty.fg.red + str(e) + sty.fg.rs)
            await ctx.send('Failed to create an application')
            return
        try:
            bot_app = await app.create_bot()
        except Exception as e:
            print(sty.fg.red + str(e) + sty.fg.rs)
            await ctx.send('Failed to create an bot to the application, the application was successfully created ...')
            return
