Why does the server receive an empty value?

Question

Mongoose

After submitting the form data to the server, an empty object is stored in the database. API checked by plstman - when sending json, everything in the database is saved correctly. In the developer console, it is indicated in the header of the post request that the data type is html text, maybe this is the problem?

Answer 1

The issue was resolved by looking at the options. Too bad I didn't understand what the problem was. . . .

Answer 2

Send data from the form in JSON format, and receive it on your back.
