Please see the image below, I am facing this problem, Whenever I refresh my BI report it gives me this error, and than I refreshs it mannually through Query Editor and do Close and load, than refreshs the BI its works. 

Following Steps I have to solve this error

1). Checked all the steps in building this combination, Spelling, fields, etc - Error remains 

2). Deleted this step, save and close file, and recreated this step --> Error remains.

3). Deleted this entire qurey related to this table and recreate query --> Error remains 

4). Built a new BI - but ERROR REMAINS  😢😢😢

Any help / suggestion, any solution here or you are welcome at rauf.anwar@zeiss.com

Good day @Anonymous 

Power Query security prevents the unintentional leakage of data - and that is what is ultimately behind the error message. The full description is quite involved and there is more than one solution. Chris Webb explains it better than I could. I would recommend his YouTube video.

Hope this helps
