TypeError: Cannot read properties of undefined (reading 'getText')

  1. Open an existing card on a board
  2. Click in the field to add a comment

研究方向
The error occurs in the comment editor when navigating with cursor keys after inserting blank lines. Investigate the comment input component in the webapp directory, likely where 'getText' is called on an undefined object. Ensure null checks are added before accessing 'getText'. The attached log may provide additional context.
