Options call fails

Grafana k6 OSS Support

Hi all,

k6 Version: k6 v0.36.0 (2022-01-24T09:50:03+0000/ff3f8df, go1.17.6, windows/amd64)

I’m trying to make an options call and it always comes back with a HTTP 405 METHOD_NOT_ALLOWED_ERROR.

As far as I can tell there appears to be some issue with the adding of the headers for an option call

  const urlParams = {
    headers: {
      'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
      'accept-encoding': 'gzip, deflate, br',
      'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36',
      'Access-Control-Request-Method': 'GET',
      'Access-Control-Request-Headers': 'companyauth',
    },
  };

const optionsResponse = http.options(Url.toString(), urlParams);

The same header params is passed onto the subsequent GET call and works fine.

any ideas?

Hi @BobRuub,

http.options takes a body as the second argument not a Params which is the third argument. So if you do

const optionsResponse = http.options(Url.toString(), null, urlParams);

it should work.

added, the null into the call and while it fixed the headers still getting an error… :frowning:

  const urlParams = {
    headers: {
      'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',

      'Access-Control-Request-Method': 'GET',
      'Access-Control-Request-Headers': 'compauth'
    },
  };

  const optionsResponse = http.options(Url.toString(), null, urlParams);

sorted,

cut down the headers to the following

const headerParamOptions = {
    headers: {
      'Origin': 'https://congo.beta.company.com.au',
      'Connection': 'keep-alive',
      'Access-Control-Request-Method': 'GET',
    },
  };

and it worked fine :slight_smile:
