fix(cc-sdk): fixed-queue-transfer

COMPLETES #< SPARK-647920 >

This pull request addresses

• Currently, blind transfer to queue was not calling task:end event when the action happened.
• Thus, as a result we were not getting any wrapupRequired in order to wrapup the call after transferring.
• This is causing an issue in widgets.

by making the following changes

• We listen for the AgentVTeamTransferred event on SDK and send out task:end event with wrapup payload.
• This will work out of the box with widgets now.

📝 Walkthrough

Walkthrough

This change introduces new logic to the TaskManager component within the Webex Contact Center plugin. Specifically, it adds a case for handling the CC_EVENTS.AGENT_VTEAM_TRANSFERRED event within the registerTaskListeners method. When this event is detected, the current task emits a TASK_EVENTS.TASK_END event with a payload indicating that wrap-up is required, followed by the invocation of the handleTaskCleanup() method to perform necessary cleanup. To verify this behavior, a new unit test is added. The test simulates the event, checks that the correct event emission occurs, and confirms that the task is properly removed from the task collection after the event is processed. Additionally, in the sample app, the call to updateButtonsPostEndCall() was removed from the toggleTransferOptions() function, so toggling transfer options no longer triggers UI button state updates. No changes were made to exported or public entity declarations.

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.

Please fix the wrapup getting enabled issue on the samples page as highlighted by Priya. Rest looks good to me.

For some reason - that issue is happening on amplify link only... not sure why.
On my local build it is not showin up.
