dataset refresh error type mismatch in Bi service

I am getting following error! BI desktop refresh processes data without any error detected. In addition I took the script of the same XYZ table and created another dataset and published it to BI and refresh was successfull without any error. What is going on here?

I read articles for trying to profile column but profiling whole dataset is not convenient as data is too large. 


Data source error: The following system error occurred: Type mismatch. Table: XYZ.




@themistoklis and others can you please help me resolve this?

Hi @AkshayB 


What I would do is to change the data tab to the correct data type in power query that should then resolve your type mismatch error.
