Azure Analysis Services: An unexpected error occured (file 'tmsavepoint.cpp, line 1503, function 'TMSavePoint::GetProxyImpl') at Microsoft.AnalysisServices.Tabular.Model.SaveChangesImpl(SaveOptions options)

Question

Use Case: We are deploying a Tabular Database to an Azure Analysis Services Instance located in West Europe, using a .NET programm.

Here is the relevant part of the C#-code:

using Microsoft.AnalysisServices.Tabular;
...
Server server = new Server();
server.Connect(connectionString); 
Database olapDb = JsonSerializer.DeserializeDatabase(olapDbScript);
server.Databases.Add(olapDb);
olapDb.Update(UpdateOptions.ExpandFull);
...

Problem: olapDb.Update() throws following exception:
An unexpected error occured (file 'tmsavepoint.cpp, line 1503, function 'TMSavePoint::GetProxyImpl')

at Microsoft.AnalysisServices.Tabular.Model.SaveChangesImpl(SaveOptions options)
...

Note: We get the same message also with SQL Server Analysis Services 2019 (Build 15.0.32.52).

What is wrong there?

Answer 1

This looks to me like you've encountered a bug. You should raise an official support ticket with Microsoft so that they can get an engineer engaged to investigate this.

Hi @Varbanov, Georgi ,

Welcome to Microsoft Q&A! Your question is related with C#, but I am not familiar with it. I suggest that you could post your question in C# forum and will get a solution quickly.

Based on my research, you could check the name of the server and the database first, it seems to be case sensitive when deployed to the server. If it is not work, please refer to this similar issue, and it resolved by CU12(15.0.35.15).
