SSMS connection error to Power BI analysis service on "Parameter already exists"

[VeraInSydney]

Dear Community,

I am trying to connect Power BI service dataset from SSMS, which was successful, however I can't process tables as it returns error message as follows : 

"

===================================

paramter name already exists
Parameter name: name (Microsoft.AnalysisServices.BackEnd)

------------------------------
Program Location:

at Microsoft.AnalysisServices.BackEnd.DataWarehouse.ConnectionStringBuilder.AddParameter(String name, String value)
at Microsoft.AnalysisServices.BackEnd.DataModelingUtility.AppendCatalogInfo(ConnectionStringBuilder connectionStringBuilder, String databaseName)

"

Please let me know if anyone knows how to resolve this.

Cheers,

Hi @VeraInSydney,

I suppose you are trying to provide duplicate parameters with the same name in the connection. please double-check your settings and connection to confirm these.

In addition, you can also take a look at the following link about a similar issue if helps:
