Hi @BhaveshPatel, 

Please run the Power BI desktop as administrator, click on File -> Open to open the report. 

Also please update Power BI desktop to the latest version 2.79.5768.1082.

Hi there,

I have tried all the suggested options but the problems seem to be in composite model APIs. The direct query table is having issues. This model is already in the production and the issue started to appear from the current month update (March 2020). I tried with the sample composite model in the other file and does not seem to be an issue. This seems to be an issue with the particular file. I am getting the below error.

Hi @BhaveshPatel, 

I would suggest you create a support ticket to let engineers look into the issue on your side.
