I am trying to create a record triggered flow that checks when the Status picklist field on the case object changes from closed to in progress. When this happens a read-only checkbox field called reopened is checked (set to true) and can never be unchecked.
When creating my starting condition for this flow I decided to use a formula and select the option to run the flow Only when a record is updated to meet the condition requirements. But despite working fine on the front end, I get this syntax error on the code that only goes away when I select to run the flow Every time a record is updated and meets the condition requirements.
What I would like is for this flow to only fire when the prior value of the status field is "Closed" and when the new value is "In Progress".
So why am I getting this error and will selecting the first open of when to run the flow cause any issues to performance or how many times this flow is checked?
