I am using the trigger - Manually trigger a flow. Then I added the trigger condition - @or(equals(triggerBody()?['Region']?['Value'],'ASIA'),equals(triggerBody()?['Region']?['Value'],'TEST Region')).


When I run the flow I got the error message "Cannot read property 'properties' of undefined". If I remove the trigger condition, I do not get the error. However, I need the flow to run based on value of the Region column. Region column is a drop-down that the user would select.
Can somebody help please?
Thank you!
