Hi All,
I am trying to customize a SharePoint list form in PowerApps. The first time the powerapp form is loaded, it is throwing error. The 'Item' property of SharePointForm1 is throwing error in "First(" function.

Error: Error When trying to retrieve data from Network
I've tried removing data source and added again but couldn't resolve the issue. The list doesn't have any lookup columns and this error is not occurring in other lists within the site.
Can anyone suggest the necessary steps to be taken to resolve this issue?
Thanks,
Kunal
