Power BI REST API - UpdateDatasource - Operation is not supported for selector

Hi,

I'm using PowerBI Rest API to update the datasource. (https://docs.microsoft.com/en-us/rest/api/power-bi/datasets/updatedatasourcesingroup)

Data sources included in this dataset: SqlServer{"server":"bXXXXXX01v\\secondary","database":"XXXXX_DB"}

My JSON:

 

{
  "updateDetails": [
    {
      "datasourceSelector": {
        "datasourceType": "SQL",
        "connectionDetails": {
          "server": "bXXXXXXX01v\\secondary",
          "database": "XXXXX_DB"
        }
      },
      "connectionDetails": {
        "server": "bXXXXXXX02v",
        "database": "XXXXX_DB"
      }
    }
  ]
}

 

 

I'm getting this error:

 

{
  "error": {
    "code": "InvalidRequest",
    "message": "Operation is not supported for selector #8"
  }
}

 

 

If I change "bXXXXXX01v\\secondary" to "bXXXXXX01v\secondary" I get this:

 

{
  "error": {
    "code": "BadRequest",
    "message": "Bad Request",
    "details": [
      {
        "message": "Bad JSON escape sequence: \\s. Path 'updateDetails[0].datasourceSelector.connectionDetails.server', line 7, position 35.",
        "target": "updateDatasourcesRequest.updateDetails[0].datasourceSelector.connectionDetails.server"
      },
      {
        "message": "'updateDatasourcesRequest' is a required parameter",
        "target": "updateDatasourcesRequest"
      }
    ]
  }
}

 

 

If the original datasource is just "server": "bXXXXXX01v", it works fine.

 

What might be the problem here?

Can I use special characters in the server option?

Hi all,

After several weeks, microsoft support found the problem.

The PBI report was developed in v1.

To solve this:

- install latest version of PBI Desktop

- Open PBI Report

- Save As with another name

- Publish new file

After this, the error is gone.

This is the code I'm using in the API website:

{
  "updateDetails": [
    {
      "datasourceSelector": {
        "datasourceType": "SQL",
        "connectionDetails": {
          "server": "bXXXXXXX01v\\secondary",
          "database": "XXXXX_DB"
        }
      },
      "connectionDetails": {
        "server": "bXXXXXXX02v",
        "database": "XXXXX_DB"
      }
    }
  ]
}
