Issue - Update Data Source Credentials through REST API failed for Web Source
I was trying to update the data source credentials through REST API (https://api.powerbi.com/v1.0/myorg/gateways/{gatewayId}/datasources/{datasourceId}) for a PBI report whose data source tpye is "Web" and it is from a CSV file on SharePoint site. I chose "OAuth2" as credential type in the body but got errors as below: It says the credentials for the web source are invalid. However I used the same credential type and same token for another PBI report (data source type is "SharePoint List" and they are pointing to the same sharepoint site), and the REST API call was made successfully. Could anyone tell me what's missing during this operation for the websource or is there anything I can do to make the call succeed.
