why my axios header instance doenst send token code example

Example 1: send token in axios header

const username = ''
const password = ''

const token = Buffer.from(`${username}:${password}`, 'utf8').toString('base64')

const url = 'https://...'
const data = {
  ...
}

axios.post(url, data, {
  headers: {
    'Authorization': `Basic ${token}`
  },
})

Example 2: axios get request with headers in token

axios.get('https://api.github.com/user', {
  headers: {
    'Authorization': `token ${access_token}`
  }
})
.then((res) => {
  console.log(res.data)
})
.catch((error) => {
  console.error(error)
})
