I too got this issue. while working on a frontend project(vue).
I don't know why it happens but I found a way around / solution.

go to your pakage.json file. go to "scripts" and add

   "scripts": {
     "fakeDB":"json-server --watch db.json"
 },

you can change "fakeDB" to what ever you want and "json-server --watch " is used to run your json db file in my case its db.json
