[BUG] Error Fetching User Info for Unparticipated Leetcode Users and incorect badge display

[nidhi2026]

What happened ?

When attempting to fetch user information for valid Leetcode users (e.g., inurownhands), an error occurs with the message:
Error fetching user info: TypeError: Cannot read properties of null (reading 'attendedContestsCount')

Despite the user being valid, the bot throws an error and fails to retrieve user info., it should rather give 0 as contest value.

When fetching user information like for fjzzq2002 from Leetcode, the bot displays the badge as [object Object] instead of showing the actual badge. This issue occurs for users who have valid badges, but the bot is not handling the badge display correctly in Discord.
