Unable to preview the data in virtual table

(0) ShareShare
ReportReport
Posted on by CU05051022-0 4
I am trying to preview a virtual table in PowerApps, but I keep getting an error message: Something Went Wrong.
The columns are loaded successfully, but the data is not displayed.
 
 

I’ve noticed that the error only occurs when the primary key is a string. If the same table uses an integer as the primary key, it works without issues.

Does PowerApps have a limitation that only allows tables with an integer primary key to be displayed?

    Not quite sure what resource you are using.
    There are some limitations when you use virtual tables.
     
    Please feel free if you have any questions.

    I am using SQL Server as an external data source, and it seems like from the documentation linked,Limitations and troubleshooting virtual tables with Power Apps - Power Apps | Microsoft Learn
    SQL resource should either have GUID or integer field.
