Walkthrough

The update in the L2Client struct involves enhancing the error handling in the L2BlockRefByLabel method. Specifically, the method now recognizes and appropriately handles an additional error message related to "unknown block." This improvement builds on existing checks for similar error scenarios, ensuring more robust error detection and management.

105-105: Enhanced error handling for "unknown block" in addition to "block not found" and "Unknown block".

Verification successful

---

The output from the executed script confirms that the error handling logic in the L2BlockRefByLabel method of the L2Client struct now includes checks for the error messages "block not found", "Unknown block", and "unknown block". This aligns with the changes described in the review comment, which aimed to enhance error handling by including these specific error messages.

The script output shows the relevant section of the code where these error strings are checked within a conditional statement. This ensures that if any of these error messages are part of the error returned by PayloadByLabel, the error is handled appropriately by setting it to ethereum.NotFound.

Given this confirmation, the review comment is accurate as it reflects the changes made in the codebase correctly. The error handling enhancement for these specific error messages has been verified successfully.

Tips

Chat

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>.
  • 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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @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.

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.
