GetTablesInGroup Is always returning a NotFound Exception

[MoTaher]

Hello everyone,

I'm facing a problem while trying to retrieve the Tables name that I'm using in my report.
I'm using PowerBi REST API in a .NET 8 project.

The function client.Datasets.GetTablesInGroup(groupId,datasetId) is returning NotFound Exception even though the dataset exists and the workspace exists and I'm displaying the report in my web application.

I think because I'm using DirectQuery mode when I'm creating my reports and not Push dataset.
How Can I get my table names please.

Thank you all.

I am not aware of such an API call. Reports don't have tables.  Semantic models have partitions which map to queries and to the underlying data sources.  

Did you mean to call Datasets - Get Datasources In Group - REST API (Power BI Power BI REST APIs) | Microsoft Learn  ?
