error in tabular model refresh within Visual studio

Hello, I hope you are doing well!

When I am trying to refresh a tabular data model within visual studio that is using a Oracle data source; I am getting the following error message :

Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] An error happened while reading data from the provider: 'Object reference not set to an instance of an object.'


NB : the refresh is working when I deployed the model on a ssas tabular model instance( weird)

any idea please ?

Thnaks in advance

Hi,

What compatibility level tabular model are you dealing with ?

Could you try switch the provider here in the project, see if other providers work. It is listed here : Supported data sources for in-memory tabular models
