Cannot create data source on gateway - PowerBIEntityFrameworkOperationException

I am trying to create a new data source on a gateway using the .NET SDK, but every call results in bad request due to a PowerBIEntityFrameworkOperationException.

 

I've tried to follow the instructions on https://docs.microsoft.com/en-us/power-bi/developer/automation/configure-credentials?tabs=sdk3#confi...

but I may have missed something.

 

string oleConnectionString = "{\"connectionString\":\"provider=SQLOLEDB.1;initial catalog=my database;data source=my server;ApplicationIntent=ReadOnly\"}";
var credentialsEncryptor = new AsymmetricKeyEncryptor(gateway.PublicKey);

var credentials = new BasicCredentials("my username", "my password");
var credentialDetails = new CredentialDetails(credentials, PrivacyLevel.Organizational, EncryptedConnection.Encrypted, credentialsEncryptor);
var oleRequest = new PublishDatasourceToGatewayRequest("OleDb", oleConnectionString, credentialDetails, "New data source");

var newDatasource = await pbi.Gateways.CreateDatasourceAsync(gateway.Id, oleRequest);

 

Things I've tried:

 

1. Creating the data source manually in the Power BI portal. This works.

2. My data source is SQL Server but I need to pass parameters in the connection string so I'm using the OleDB provider. As a test I've tried change the data source type to "SQL" and the connection details to 

"{\"server\":\"my server\",\"database\":\"my database\"}". This results in the same PowerBIEntityFrameworkOperationException exception.
3. I've tried calling the UpdateDatasource method to change the credentials on a manually created data source. This worked, which  suggests that I'm passing the credentials correctly.

I'm receiving the same error. Also trying it in the sandbox (https://docs.microsoft.com/en-us/rest/api/power-bi/gateways/createdatasource) returns the same error.
