Unable to process template language expressions for action 'Condition' at line '0' and column '0' - within PowerBI

Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'The template language function 'length' expects its parameter to be an array or a string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#length for usage details.'.

As above, the flows. The 'Title' column in my SPO List is a simple Single Line Text field - where am I going wrong here, I'm racking my brain, the examples I've viewed make this look so simple, is the PowerBI integration causing the issue?

Effectively checking if the Title column output matches the PowerBI Data Field, if Yes, then just update the Name/UserID etc. If No then create a new field with the data from PowerBI. The flow is failing at the Condition and I'm very lost, any help would be greatly appreciated.

    @CJ-WEL ,
    Try to use empty function for the check.

    empty(outputs(….)) is equal to true

    Hi,

    While this wasn't the exact solution it did help me locate the problem so I will accept and place the solution below, appreciate your help.


    It was how I had set up my steps, I believe I created a step instead of an action on the previous step, which didn't allow me to pull through the required data.
