Exception in function shouldRetryRequest() when checking HTTP methods to retry

In function shouldRetryRequest there’s this block of code

    // Only retry with configured HttpMethods.
    if (!err.config.method ||
        config.httpMethodsToRetry.indexOf(err.config.method.toUpperCase()) < 0) {
        return false;
    }

that fails evaluating second condition, because httpMethodsToRetry is an object, not an array.

Below goes the output from dev console, when the breakpoint was set on the line given above ^^^:

config.httpMethodsToRetry
{0: "GET", 1: "HEAD", 2: "OPTIONS", 3: "DELETE", 4: "PUT"}

That looks different from what gets set in raxConfig

    const raxConfig = {
    ....
        
      // HTTP methods to automatically retry.  Defaults to:
      // ['GET', 'HEAD', 'OPTIONS', 'DELETE', 'PUT']
      httpMethodsToRetry: ['GET', 'HEAD', 'OPTIONS', 'DELETE', 'PUT'],
    }

v0.19.0-beta.1. Please see my comment. Now options are completely whitelisted and it doesn’t accept raxConfig.

I am also getting error,

Here is my relevant code,

axios.defaults.raxConfig= {
  // Retry 3 times on requests that return a response (500, etc) before giving up.  Defaults to 3.
  retry: 3,

  // Retry twice on errors that don't return a response (ENOTFOUND, ETIMEDOUT, etc).
  noResponseRetries: 3,

  // Milliseconds to delay at first.  Defaults to 100.
  retryDelay: 0,

  // HTTP methods to automatically retry.  Defaults to:
  // ['GET', 'HEAD', 'OPTIONS', 'DELETE', 'PUT']
  httpMethodsToRetry: ['GET', 'DELETE', 'PUT', 'POST'],

  // The response status codes to retry.  Supports a double
  // array with a list of ranges.  Defaults to:
  // [[100, 199], [429, 429], [500, 599]]
  httpStatusCodesToRetry: [[100, 199], [429, 429], [500, 599]],

  // If you are using a non static instance of Axios you need
  // to pass that instance here (const ax = axios.create())
  instance: axios,

  // You can detect when a retry is happening, and figure out how many
  // retry attempts have been made
  onRetryAttempt: (err) => {
    const cfg = rax.getConfig(err);
    console.log(`Retry attempt #${cfg.currentRetryAttempt}`);
  }
};
const id = rax.attach(axios);

And here is the error,

TypeError: config.httpMethodsToRetry.indexOf is not a function
