Unable to preview the data in virtual table

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?

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.
