Update item in child list, getting error "Fix invalid expression for the input parameter of operations "Get_items'

Hello,

 

Here are screen shots of my flow, can you tell me how to fix the error? The flow is to create a new item in the child list if it doesn't exist and update item if it does exist.

Hi @trishmalloy ,

 

Please paste the following expression in Filter Query:

Title eq '@{triggerOutputs()?['body/Title']}'

Hello @trishmalloy 

You have to fix the Filter Query field in your Get items action. See my example

Flow.Filter query.With dynamic content.jpg

It looks like you accidentally wrote the expression for the trigger title as a text instead of an expression. Anyway, you should be able to choose it under the Dynamic content list.

Hope this helps you on the way.

Kind regards, John

This fixed the error, but the flow still isn't updating existing items. I can post another request for help. Thank you!
