I want to add trigger condition to flow that resides with a solution, in order to stop it retriggering .
I have added my expression to a compose action it there are not issues. When I add the same expression with the @ prefix to the trigger condition it errors

here is he expression
@not(equals(triggerOutputs()?['body/TestStatus/Value'], 'Terminated'))
By are process of elimination it appears the not() expression is the issue , even in this simple test which also fails with the same error .. er am I missing something here?
