BadRequest error when using Create Datasource method.

[gagusz]

Hi,

When trying to invoke a method followin instructions from documentation (https://docs.microsoft.com/en-us/rest/api/power-bi/gateways/create-datasource), I encountered the errors I am not able to find anywhere on the Internet:

{

    "error": {

        "code": "DM_GWPipeline_UnknownError",

        "pbi.error": {

            "code": "DM_GWPipeline_UnknownError",

            "parameters": {},

            "details": [

                {

                    "code": "DM_ErrorDetailNameCode_UnderlyingErrorMessage",

                    "detail": {

                        "type": 1,

                        "value": "Invalid Ciphertext size. Expecting cipher text of atleast length, 344. Provided cipherText length, 54"

                    }

                },

                {

                    "code": "DM_ErrorDetailNameCode_UnderlyingHResult",

                    "detail": {

                        "type": 1,

                        "value": "-2146233296"

                    }

                }

            ],

        }

    }

}

Hi @gagusz ,

First, please make sure the gateway didn't install in Virtual network. Not sure if the credentails part cause this error... Please refer the following links to configure credentails, later check if it can work well...

By C#:

Configure credentials programmatically for Power BI

// Basic credentials
var credentials = new BasicCredentials(username: "john", password: "*****");

var credentialsEncryptor = new AsymmetricKeyEncryptor(publicKey);
var credentialDetails = new CredentialDetails(credentials, PrivacyLevel.Private, EncryptedConnection.Encrypted, credentialsEncryptor);
