Gateways - Update Datasource request fails: Invalid Ciphertext size.

When I make a request to update datasource for a gateway, I get an error about ciphertext that seems rather confusing since I'm just using Basic credentials. Any idea what this means?

PATCH https://api.powerbi.com/v1.0/myorg/gateways/(my-gateway-id)/datasources/(my-data-set-id)

 

 

 

{
  "credentialDetails": {
    "credentialType": "Basic",
    "credentials": "{\"credentialData\":[{\"name\":\"username\", \"value\":\"my_username\"},{\"name\":\"password\", \"value\":\"my_password\"}]}",
    "encryptedConnection": "NotEncrypted",
    "encryptionAlgorithm": "None",
    "privacyLevel": "None"
  }
}

I'm getting the same error when trying to update basic credentials. Much appreciated if anyone can shed some light on to what's causing this error. Thanks.

Hi @xli629b ,

 

I suggest you to refer to this post first to create a database without database name by using RESTful API: https://community.powerbi.com/t5/Power-Query/Gateway-advises-Sql-Database-function-is-unsupported/m-....

 

Then, try this:
