Summary

I'm getting the following error after upgrading axios to version 1.2.2:

TS2339: Property 'Authorization' does not exist on type 'AxiosHeaders | Partial<RawAxiosHeaders & MethodsHeaders & CommonHeaders>'.
Property 'Authorization' does not exist on type 'AxiosHeaders'

The same snippet of code is working on version 1.2.1:

import axios from 'axios';

axios.interceptors.request.use((request) => {
    request.headers
        ? (request.headers.Authorization = `Bearer ${token}`)
        : (request.headers = { Authorization: `Bearer ${token}` });
});

Environment

• Axios 1.2.2
• Node.js 18.12.1
• OS: Ubuntu 20.04.4 LTS (WSL2)
