While trying to develop mfe from localhost its not working

I have tried configure learning mfe in local after running npm start:
http://localhost:2000/course/course-v1:edX+DemoX+Demo_Course%20to%20view%20the%20demo%20course
but this url is showing like this below:

Try http://localhost:2000/course/course-v1:edX+DemoX+Demo_Course

It looks like you accidentally included the phrase “to view the demo course” in your URL.
