Trigger SharePoint When a file is created/modified properties only is missing properties!

I am using the trigger SharePoint - When a file is created or modified (properties only) and it appears to be missing properties at run time.


In the editor I see the properties I want to work with:


When it runs, the trigger doens't have the properties and the value doesn't show up in my further actions

I have encountered the same problem. On run time, a condition fails as the modified by appears to be NULL. When I click open the trigger (output used in condition), I see no mention of modified by or editor, only author. This Flow was working earlier. Something changed?


Error i'm getting: 

InvalidTemplate. Unable to process template language expressions for action 'Condition_-_Modified_by' at line '' and column '': 'The template language function 'endswith' expects its first parameter to be of type string. The provided value is of type 'Null'. 

Edit: this prevented my flows from going in an error state. However, the condition i set to check whether the item was modified by a service account (such as the one used in the flow) did not work anymore as the variable remained empty. This caused my flow to enter an endless loop. Created a ticket for this issue.


As a workaround, I have added the initialize variable action as shown below before my condition and updated my condition to use the output variable 'Editor' from this action. Maybe this can be a temporary fix for you too. Would like to hear if something has changed in the backend that caused this issue to show up.
