HTTP Requests broken after changing flow trigger

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

Our team currently has a flow that has been working well mostly, but due to some errors in the Power Apps form, we changed the trigger of the flow from "Start flow whenever a list item is updated" to a Power Apps trigger, that starts whenever the form is submitted. This has eliminated the errors we were having, but seems to have messed up every HTTP request to Sharepoint we have in the flow (there are several). One of the error messages is pasted below (along with the step before error). The old copy of this flow that triggers with the list item change works perfectly with this exact set up. 

 

Any ideas why the change causes this error?

    Hi @Anonymous 

     

    Based on the error, the filter expression variable is not getting populated with the sharepoint item id. While changing the trigger it must have deleted all references to the trigger outputs from the dynamic data and you have to identify those and get that data either from Power Apps as inputs or a get item action after the power apps trigger where you can pass the item id from Power Apps again. 

     

    Hope this Helps!

    Hi @yashag2255 

     

    Sorry for delayed response - was out for holidays!


    We've got a get item action immediately following the PowerApps trigger, which retrieves item id (screenshot below).  I think in the screenshot though its trying to get the ID of a group member on the SP site, not of the item. For a lot of the http requests the error is just a bad gateway error.
