  relevant file	frontend/components/KanbanBoard/AssignedUserFilter/index.tsx
  suggestion	Consider creating a CSS class for the avatar image styling instead of inline styling. This can improve code readability and maintainability. [medium]
  relevant line	className='inline-block h-9 w-9 rounded-full ring-2 ring-white'

  ---

  relevant file	backend/src/index.js
  suggestion	It would be good to handle potential errors that might occur during the execution of 'minioClient.getObject'. This can be done by wrapping the call in a try-catch block. [important]
  relevant line	const result = await minioClient.getObject(BUCKET_NAME, file);
