40147: Supervise instruction failed: missing or invalid 'contact_uri'

This error occurs when you issue a Supervise instruction and the Supervisor's Worker attributes do not include a valid contact_uri. TaskRouter stores Worker attributes as JSON and needs contact_uri to know whom to call.

• The Supervisor's Worker attributes do not include contact_uri.
• The Supervisor's Worker attributes are not valid JSON, so TaskRouter cannot read contact_uri.
• The contact_uri value is invalid.
• The contact_uri value does not point to a valid phone number or client ID for your implementation.

• Update the Supervisor's Worker attributes to include a valid contact_uri.
• Make sure the Worker attributes are valid JSON before you save them.
• Set contact_uri to the phone number or client ID that should receive the Supervise call.
• Fetch the Worker after updating it to confirm the attributes were saved, then retry the Supervise instruction.
