A few things were causing issues with Slack alerts:

  • Text fields for each block have a 3000 character limit
  • The official client has a ridiculous default retry policy
  • Final errors should never be retried

This has all been fixed.

Summary by CodeRabbit

  • New Features

    • Introduced a new error handling mechanism for alert delivery, allowing specific errors to skip retries.
    • Added methods for improved formatting of error messages sent to Slack, including truncation for long messages.
  • Bug Fixes

    • Enhanced error handling for Slack-specific errors to prevent unnecessary retries.

Walkthrough

The changes involve modifications to the OrgIntegrationRepository and DeliverAlertService classes. The WebClient instantiation in OrgIntegrationRepository now includes a retry configuration. In DeliverAlertService, a new error class SkipRetryError is introduced to manage specific error scenarios during alert delivery, enhancing error handling and message formatting. Additional methods for formatting error messages and truncating text for Slack are also added, while the existing switch statement structure remains intact.

Changes

File Path Change Summary
apps/webapp/app/models/orgIntegration.server.ts Modified WebClient instantiation to include a retry configuration with specified settings.
apps/webapp/app/v3/services/alerts/deliverAlert.server.ts Introduced SkipRetryError class, added error handling in call method, and implemented methods for formatting error messages.

Poem

In the code where rabbits play,
New retries hop along the way.
Errors caught with gentle care,
Formatting messages, a joyful flair.
With each change, we leap and bound,
In our code, new wonders found! 🐇✨

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>, 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.

72-80: LGTM! Consider verifying retry configuration and addressing other objectives.

The changes to the WebClient configuration align with the PR objective of addressing the retry policy issue. The new configuration limits retries and sets reasonable timeouts, which should help prevent excessive retries.

Please consider the following points:

  1. Verify that the retry configuration values (2 retries, 5s max timeout, 10s max retry time) are optimal for your specific use case.

  2. The PR objectives also mention issues with text length limits and final errors handling. These are not addressed in this file. Ensure that these objectives are covered in other parts of the PR.

To help verify the changes, you can run the following script to check for any other usages of WebClient that might need similar configuration:

This will help ensure consistency across the codebase in handling Slack client configurations.

✅ Verification successful

To continue the verification, please run the following script to search for other WebClient instantiations in TypeScript files:


Verified no additional WebClient instantiations.

There are no other instances of WebClient being instantiated outside of apps/webapp/app/models/orgIntegration.server.ts. This ensures that the retry configuration changes are consistently applied.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for other WebClient instantiations
rg --type typescript 'new WebClient\(' -g '!**/orgIntegration.server.ts'

Length of output: 109


Script:

#!/bin/bash
# Search for other WebClient instantiations excluding orgIntegration.server.ts
rg 'new WebClient\(' -g '*.ts' -g '*.tsx' -g '!**/orgIntegration.server.ts'

634-636: Ensure error messages are properly formatted and truncated.

The use of this.#wrapInCodeBlock enhances error message formatting and ensures messages adhere to Slack's length limitations. This helps prevent errors due to message length exceeding Slack's limits.


746-748: Consistent formatting of error messages in Slack alerts.

Applying this.#wrapInCodeBlock to the error messages improves readability and maintains consistency across different alert types sent to Slack.


846-848: Appropriate handling of deployment error messages.

Wrapping the deployment error messages with this.#wrapInCodeBlock ensures that large error messages are properly formatted and truncated, preventing potential issues with Slack's message length restrictions.


1027-1033: Properly handle Slack 'invalid_blocks' errors to prevent retries.

By checking for the "invalid_blocks" error and throwing a SkipRetryError, the code prevents unnecessary retries for errors that won't succeed on subsequent attempts. This enhances the efficiency of the alert delivery system.
