requests are not sent from the server

I don’t know how to explain it correctly.
In general, I can’t make a request to my server from the project using: axios, needle, fetch, it doesn’t even send the request, it just gives out `data: ”I don’t know how to fix it, sorry I don’t even know how to explain it to you
There is no request on the server side.

But if I start using third-party programs like insomnia and stuff like that.
It sends and works. Maybe someone has encountered this problem
standart request:

axios.post('http://localhost:3000/params..') // return data: ''
