Refresh error - There is no valid Delta table at this location
Hi rhoex ,
Please verify if this limitations is causing the error you are experiencing
Microsoft doesn't support dataflow or semantic model refresh using OAuth2 authentication when the Azure Data Lake Storage Gen2 (ADLS) account is in a different tenant. This limitation only applies to ADLS when the authentication method is OAuth2, that is, when you attempt to connect to a cross-tenant ADLS using an Microsoft Entra ID account. In this case, we recommend that you use a different authentication method that isn't OAuth2/Microsoft Entra ID, such as the Key authentication method.
Another point is as you have mentioned you are using VNet + Private Endpoints on storage account so please configure a Vnet gateway and re check.

I hope this information helps. Please do let us know if you have any further queries.
Thank you
Can you please specify networking setup? It looks like a network issue to me. Power BI Service and Power BI Desktop expect to have the same behavior (if networking is configured as it should).
