I created an SPFx solution almost a month ago. That time, it was working fine, but today, it started getting the below error which was quite strange. After doingg lots of research, I got to know there was some malicious issue observed by NPM during the security check.

 

NPM security has decided to remove the "Flatmap-stream" and "[email protected]" package. The official Note from NPM can be found here.

 

On November 26, 2018, the npm package manager released security advisory 737 regarding the flatmap-stream package. It was determined that this package was malicious, and contained harmful code. In addition, the popular event-stream package was modified to make use of the harmful flatmap-stream package.
