Entity Form - Critical error when inserted & linked to Data source

[ghostwhowalkz]

Hi,

I'm trying to insert an entity form (i know, experimental), however I keep running into this error just after it loads the data source:

"WebAuthoring abnormal termination.

ReferenceError: Connection is not defined","setPromise":"[function]","exception":{}}

I've briefly tried an entity form in the past, and didn't have an issue then. I've tried with a variety of different custom entities, some brand new just to test it, and it results in the same error, everytime. What could be the issue?

Hi ghostwhowalkz,

Are you using PowerApps for Web? Which player are you using?

I just tried with the Entity Form control on both Web player(Edge) and Desktop studio, it works either for the Custom entity or the Standard entity. I don’t get the error message you mentioned.

If you are using the web player, please try to clear cache and sign in with InPrivate mode to see if it will work.

Please try again with it. If you are still having the issue, please feel free post back.

Best regards,
Mabel Mao
