Condition of Flow failing

Posted on by T_LYNCH

I am attempting to move data from one SharePoint List to another SharePoint List and the condition piece keeps of the flow is failing and giving me this error:

Unable to process template language expressions for action 'Condition' at line '0' and column '0': 'The template language function 'length' expects one parameter: an array or a string the length of which is returned. The function was invoked with '2' parameters. Please see https://aka.ms/logicexpressions#length for usage details.'.

Below is a snippet of the condition. It may be the length(body('Get_items')?['value'],0) that I have on the left side as an expression.

@T_LYNCH ,

There is no need for 0 inside your formula. The length function requires only one parameters.

length(body('Get_items')?['value'])

As I figure it out, you want to check if the action Get Items returned some info in 'value' parameters. For that you can use also:

empty(body('Get_items')?['value']) equals true

Hope it helps !

@gabibalaban I am now getting a different error. I think I've tested so many different methods and already have data in the list. I will try again in the morning and let you know if that works. Good news is that I got farther than ever before. Thank you so much for your help!
