- Cannot read properties of undefined (reading ‘block’)
Explanation: This error occurs when there’s an empty block in Blockly that the application cannot process.
Solution: Delete the empty block or fill it with the appropriate content to resolve the issue.
- The value of “offset” is out of range. It must be <= 0.
Explanation: The game contains media (images or video) that were copied and pasted directly into the task editor. This embeds the files inline, causing the game to exceed the allowed size limit.
Solution: Re-add the media using the Image button in the task text toolbar, or via the Media tab. This uploads the file properly instead of embedding it, and will resolve the error.
