14230: Dial->Conference: Invalid WorkflowSid

This error occurs when a TaskRouter-based voice flow tries to use a workflowSid, but the value is not a valid TaskRouter Workflow SID. A Workflow SID identifies the Workflow that routes Tasks in a Workspace, and valid Workflow SIDs use the WW prefix.

• The workflowSid value is malformed or incomplete.
• The value does not reference a Workflow SID with the expected WW prefix.
• The Workflow SID does not exist in the TaskRouter Workspace handling the call.
• The Workflow was deleted or changed, but your application is still sending the old SID.
• Your application is passing a different resource SID, such as a Workspace SID or TaskQueue SID, instead of a Workflow SID.
• A configuration or environment variable points to the wrong account, Workspace, or deployment environment.

• Verify that the workflowSid value is the exact SID of an existing TaskRouter Workflow.
• Confirm that the Workflow belongs to the Workspace your application is using for this call flow.
• Review your application configuration, environment variables, and templates for typos or outdated SID values.
• Make sure you are passing a Workflow SID that starts with WW.
• If the Workflow no longer exists, create or select the correct Workflow and update your application to use that SID.
• Test by fetching the Workflow from the TaskRouter API for the expected Workspace before using it in your routing flow.
