Security insight Alert rule Action requires triggerUrl

When trying to send a PUT request to "/alertRules/{ruleId}/actions/{actionId}" to link an Alert Rule to a Playbook I get the following error:
`Required property 'triggerUri' not found in JSON. Path 'properties', line 1, position 701.`
This triggerUri is not getting returned when requesting al current actions with the GET request.

Compare the GET response for current alert-rule actions with the PUT request schema for /alertRules/{ruleId}/actions/{actionId}. Trace how the triggerUri property is represented in the API specification, then verify that the schema and returned action data agree and that the PUT request no longer fails validation.
