Condition Error

Posted on by Community Power Pla... Microsoft Employee

I built a flow to generate an approval e-mail when an item is added to a list. The e-mail generates successfully, but when a decision is given by the approver, the workflow then fails at the condition stage. The following error displays:

Unable to process template language expressions for action 'Condition' at line '1' and column '2603': 'The template language expression 'equals(body('Start_an_approval')?['response'], 'Approve')' cannot be evaluated because property 'response' cannot be selected. Array elements can only be selected using an integer index. Please see https://aka.ms/logicexpressions for usage details.'.

Has anyone seen this? If so, what should I be looking for?

Please post a screen shot of your Flow - that will make it much easier to assist. The screen shot should show the Flow in design mode - not the results of a run.

Your issue stems from the fact that you have an approval action inside of a loop. First, the Flow will pause on each approval until a response is received. I believe the error occurs because Flow doesn't know whcih approval you are referring to.

Will you have more than 1 approver?

Hey Scott,

I apologize for the delay as I was out of the office. I am pretty new to this functionality so I may need a bit more direction on this. When you say the approval action is inside of a loop, what is the way you would mitigate that?

And yes, there will be times when there are multiple approvers.

Thanks
