Hi @kevingeorget,
Could you please share a screenshot about your flow's configuration?
Do you want to pass the whole Person field value (A record value) from your app to a flow?
If you want to pass the whole Person field value (A Record value) from your app to a flow, I afraid that there is no way to achieve your needs in PowerApps currently.
Currently, a flow could only accept Strings Text as parameters passed from an app. Passing a record value from an app to a flow is not supported within PowerApps.
In addition, if you want to assign a value to a Person field within the "Create Item" action in your flow, I think the Email value or Claim value of a Person field value could achieve your needs. I have made a test on my side, please take a try with the following workaround:
Flow's configuration:
App's configuration as below:
Set the OnSelect property of the "Trigger Flow" button to following:
'20190122_case15'.Run(DataCardValue8.Selected.Claims)
Or
'20190122_case15'.Run(DataCardValue8.Selected.Email)
On your side, you should type following:
'YourFlowName'.Run(YourPersonFiledValue.Claims)
Please take a try with above solution I provided, then check if the issue is solved.
Best regards,
