TFS data set update

[Anonymous]

Hello friends!

I have a PowerBI dashboard that is updated according to the existing data set to the Visual Studio Team System (now DevOps). But since a few months ago it is not updated nor is it possible to make the connection correctly, it generates the following error message:

Error del origen de datos We cannot convert the value null to type Text.. The exception was raised by the IDataReader interface.

Please download the pbix file and open the report in Power BI desktop, in edit queries, please check where the data is wrong and remove it try refresh again.

It did not work Even, it does not enable the option to edit the query. It only allows you to configure the data source.

If I try to create a new data source, using the Azure Devops (Beta) connector, after entering the Organization and Project data, an error is also generated:

Unable to connect
An error was encountered while trying to connect.
Details: "Access to the resource is prohibited."

The strangest thing is that it brings partial data (as they existed until a few months ago) but it does not load them all.

Again, I thank you for your help and directions to solve my problem.

Regards!
