Walkthrough

This pull request updates the handleTinyGridColumnsSlots function in the canvas API. The modification ensures that the columns variable is always an array by explicitly checking if node.props?.columns exists as a valid array. If not, it defaults to an empty array, preventing runtime errors during iteration.

Changes

File	Change Summary
packages/canvas/.../useCanvas.js	Updated handleTinyGridColumnsSlots to safely assign columns as an array, avoiding iteration errors on invalid data.

Poem

I'm a little rabbit, hopping through the lines,
Fixing code with carrots, making every check shine.
I nibble bugs away as I traverse the code,
With every careful hop, a smoother path is showed.
In fields of digital green, my work is clear and bright,
Celebrating each change with a joyful bunny light!

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
