This pull request updates the findOpenGames function in the backend to ensure that the players array in each game is transformed to include only the id and username fields. This is necessary for the frontend to properly display player data while keeping unnecessary and sensitive information excluded.

Changes Made:

Updated the findOpenGames function in api/hooks/customGameHook/index.js:

• Transformed the players array using the map() method to retain only id and username.
• Filtered games to include only those with fewer than 2 players.
• Enhanced error handling to check for empty game results.
• Maintained all other game properties while transforming the players array.

Testing:

Unit tests were created and executed to validate
The unit tests ensure consistent behavior and compatibility with the frontend requirements.
