Preview.Error: The current preview value is too complex to display when using WebAPI
Hi, I am trying to use Web API to deliver Data to end user. My Developing environment is: 1. windows server 2019: to develop Power BI 2. windows server 2019: to develop Web API...
I overcome this issue myself.
First, the difference between Edge and IE might caused by the browser security settings I guess.
Second, the bottleneck is not on the Web Connector and it's on the JSON Connector.
Because I save the JSON as file and import it into Power BI using JSON Connector, then it shows me the same message:
"Preview.Error: The current preview value is too complex to display"
Finally I edit my Web API making it return in XML format.
My report just come alive again!!!!
I sacrifice the file size and choose XML Connector.
Hey, it might be a Power bi issue, if you don't mind me asking this data you are trying to pull is from which platform?
