/oath/token end-point stopped returning valid response

Hi, after some time coding on my express back-end, the /oath/token end-point suddenly stopped returning a valid response.

Expected behaviour is to receive a “data: { access_token, …}” property.

What I receive is “nonsense” characters: “data: c�@�lf��>��a���9!и鱺���’c��…”

This is the code for getting the token:

const getAuthToken = async (): Promise<string | null> => {
  const options: AxiosRequestConfig = {
    baseURL: DOMAIN,
    url: '/oauth/token',
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    data: {
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      audience: AUDIENCE,
      grant_type: 'client_credentials',
    },
  };

  try {
    const response = await axios(options);

    console.log(response.data);

    if (response.status === 200) return response.data.access_token;
    return null;
  } catch (err) {
    console.log(err);
    return null;
  }
};

This worked beautifully until an hour ago, when it just stopped providing the expected response.

Thank you,
Martin

Problem solved.

I had to add ‘accept-encoding: application/json’ to my Axios ‘headers’ to be rid of the problem. I still have no clue why this worked before, nor why it suddenly stopped working. But this fixed the issue.

Hey there @iphonelynden welcome to the community and thanks for following up on this!

I know 'content-type': 'application/json' is typically included like you have it, but I haven’t seen where accept-encoding: application/json is required so thanks for the heads up, hopefully this helps someone else in the future!

Thanks @ty.frith , I have a sneaking suspicion that it is related to Axios release 1.2.0 a few days ago, but haven’t been able to confirm. They did do something to their AxiosHeaders class at least.
