This widget could not be displayed.

Your code is passing the wrong type of data into the connection handler, or you aren't importing the correct libraries for that call.

whats mean ??? can you please give example that work ???? also which user permission need for connection thanks

It means your code is doing something the library is not built for, it's making a call that can't be handled. I can't really tell you more than that, the error message is referring to code you have not posted. I can't give you an example that works, because I have no idea what you're doing here, and it's not the code that's failing anyway. Users trying to use REST have the same rights that they would get if they logged into the UI
