Hi, The error that you are receiving while testing the JSON connection from the Web Design Studio is due to the limitation of the Denodo Platform Express version. The sources with the Denodo Browser client cannot be used to retrieve data from CSV, JSON or XML files in the Denodo Express version. To know the limitation imposed on the Denodo Express, refer to the [Restrictions of Denodo Express]( section of the Denodo Platform Installation Guide. If you would like to get a full featured trial license for Denodo, which would allow you to perform this operation in Denodo, please contact our Sales Team at or fill out the contact form at Hope this helps!

Hello Sir, I used Datasource as JSON and many times called API and created base views in denodo but never faced this issue. This is also JSON Datasource which I created to get Refresh Token from API. My question is just can we use multipart/form-datain Denodo? If yes how we can do it. Thanks

Hi, I understand that you are using the HTTP Client as the Data Route method and it's supported in the Express version. Regarding the HTTP error 401, it occurs when the credentials provided for accessing the API is not correct. So, please check the authentication credentials provided are valid. Also, to get the access token from form-data, you could add the below header in the JSON data source configuration. `Content-Type: multipart/form-data` Check if this works for you. Hope this helps!
