Internal Error 500 Update UpdateDatasetParameters api endpoint

[jsilva24]

Currently receiving a 500 with the message

{"Message":"An error has occurred."}

And no other details. I am trying to update 3 paramters in my dataset where one  defines the url for an odata datasource, the other is a token for auth, and the last one is an Id that we use in the odata service to identify the customer.

It seems to be specific to one customer as we've tried with others before. Below is the gist of the request that returns the 500 with some values replaced by bold text

POST https://api.powerbi.com/v1.0/myorg/groups/guid/datasets/guid/Default.UpdateParameters HTTP/1.1
Host: api.powerbi.com
Authorization: SomeAuth

Request-Id: some id

{
"updateDetails": [
{
"name": "ClientId",
"newValue": "guid"
},
{
"name": "ODataUrl",
"newValue": "an odata url"
},
{
"name": "AuthToken",
"newValue": "SomeAuthToken"
}
]
}
