power-bi gateways update datasource

Hello All,

Thanks for reading My Email.

Currently Im trying to configure the Power Bi Dataset using a Service Principle, which is using Common Data Service as Connection DataSource.

I was able to successfully take over the DataSet. But when I try to configure the Datasource using patch request it throwing a 400 Bad Request.

Can Someone point me to the correct direction?

 I already did enable API in Tenant settings for entire Organization and provided Power bi adminstrator role to Service Principle .

Below is the Sample Code

Invoke-PowerBIRestMethod -Url "gateways/$($BounGateway.value.gatewayId)/datasources/$($BounGateway.value.datasourceId)" -Method PATCH -Body $credentialDetails -VERBOSE

Below is the Body

{
  "credentialDetails": {
    "credentialType": "OAuth2",
    "credentials": "{\"credentialData\":[{\"name\":\"accessToken\", \"value\":\"eyJ0....fwtQ\"}]}",
    "encryptedConnection": "Encrypted",
    "encryptionAlgorithm": "None",
    "privacyLevel": "None"
  }
}

Regards

Karthik
