I want to create a flow that every time a new calendar event is created with at least one attendee a new page is created in onenote. It seemed pretty straightfoward but I am getting a trigger error on "When a new event is created (V3)". I even tried to make it really simple without the condition of more than zero attendees and it still gives me the same error.
There's a problem with this flow's trigger
Details It hasn't been triggered successfully in the last 28 days
Unable to process template language expressions for trigger 'When_a_new_event_is_created_(V3)' at line '1' and column '40153': 'The template language expression 'concat('Meeting-', triggerOutputs()?['body']['subject'])' cannot be evaluated because property 'subject' cannot be selected. Please see https://aka.ms/logicexpressions for usage details.'.
