React component type.name is some abstract letters

In my app i need to know children.type.name. In my test project i get what i expect

const TestChild2 = () => <td>b</td>;

but in my "production" project it is just "n" or "Ez" or some other random letters.

import React from 'react'

const InputCell = (props) => {

    console.log('hi');
    return <td>hi</td>;
}

export default InputCell;

Why does that happen? I use the same version of browser and same version of react ("react": "^16.13.1")in both projects.
