Request data type change to string on retry

[tomerparizer]

Hey

I see a weird behavior happening inside the retry mechanism
Once inside the retry phase the request body change to string instead of JSON
As you can see in the simple example below

const axios = require('axios');
const axiosRetry = require('axios-retry').default;

axios.interceptors.request.use((config) => {
  console.log('in interceptor', config.data, typeof config.data);
  return config;
});

axiosRetry(axios, { retries: 3, retryCondition: () => true });

async function main() {
  try {
    const body = {
      name: 'example',
    };

    const { data } = await axios.post('http://localhost:3030/return500', body);
    console.log('got data', data);
  } catch (e) {
    console.log('got an issue', e.message);
  }
}

main();

The outcome is:

in interceptor { name: 'example' } object
in interceptor {"name":"example"} string
in interceptor {"name":"example"} string
in interceptor {"name":"example"} string
got an issue Request failed with status code 500

Can you please help?

Thanks
