Creating a SP when an item is created or modified flow - Badgateway error

I'm doing the following 


  • Create Empty Flow
  • Add SharePoint Trigger + select 'when an item is created or modified'
  • Type in your SharePoint Site Address + select your list
  • + New Step
  • Add Action
  • Add SharePoint Connector
  • Choose Create item Action
  • Set your Site Address + Select list Name
  • When all your new properties show up, click one of them
  • Available fields to copy will show on the right (came from your original item)
  • Select the field, when finished select 'Create Flow

The purpose for this is to have items in one contact list whenever they are updated or a new one is created have it all copied to a master list. I keep getting sent back with the following error.


List data validation failed. clientRequestId: 94086bb2-be3a-4cd8-a912-418ef1684068

Hi @rdalrymple,


There should be an error description within the Create Item action, would you please share it here?

Further, it would be more helpful if you could share the Flow configuration and the running details, better in screenshot.

Gnerally, Bad Gateway error should happen when the Request is not valid. Which means the data input in the Create item is not available for the corresponding list to create a new item.
