"Failed to load [data source]. An error occurred on the server."

On loading of my application I get red error message banner.  The message is as follows:

 

"Failed to load [data source]. An error occurred on the server. Server response: An error occurred when trying to create a controller of type 'SharePointListTableDataController'.  Make sure that the controller has a prameterless public constructor."

 

[data source] could be any one of the data sources I use (about 7 SharePoint Online lists).  Which one shows up is reasonably random.  Sometimes it doesn't appear to affect the operation of the application, other times some buttons will be broken, or I won't be able to change/submit data.

"Failed to load [data source]. An error occurred on the server. Server response: An error occurred when trying to create a controller of type 'SharePointListTableDataController'.  Make sure that the controller has a prameterless public constructor."

Yeah...it's working fine Today. 

I think Microsoft Resolve this issue .

Issue just appeared for me. What's the resolution?

I didn't do anything. I only waited and it works.

Hmmm. I spent most of my spare time yesterday trying to figure out what I am doing wrong. Maybe I should just wait and see if it fixes itself too. Frustrating if I have to park a project and wait for it to fix itself when something goes wrong. Thanks for your response
