user-api

Hi, I'm currently working on a task to migrate my corporate users from current AnA service to fusionauth.
Part of the initial stages is writing a script (I decided to go with node js) to check if any of the users to be migrated already exist in fusionauth but I ran into the issue detailed below. It's worth mentioning that I can't use any node library other than the core once for technical reasons, this includes not installing fusionauth API.
Node code snippet where the error raised:

const apiToken = '<REQUIRED_API_TOKEN>';

function checkUserByEmail() {
  const options = {
    hostname: '<OUR_DOMAIN>.fusionauth.io',
    path: '/api/user/<USER_EMAIL>',
    method: 'GET',
    headers: {
      "content-type": "application/json",
      Authorization: apiToken,
    }
  }
  const req = https.request(options, (res) => {
    res.setEncoding('utf8');
    process.stdout.write(`STATUS: ${res.statusCode}\n`);
    process.stdout.write(`HEADERS: ${JSON.stringify(res.headers)}\n`);
    res.on('data', (chunk) => {
      process.stdout.write(`BODY: ${chunk}`);
    });
    res.on('end', () => {
      process.stdout.write('Response ended!');
    });
  });
  req.on('error', e => process.stdout.write(`${e.name}: ${e.message}`));
  req.end();
 .
 .
 .
}

The error I'm getting is:

STATUS: 400
HEADERS: {"date":"Tue, 12 Jul 2022 18:31:00 GMT","content-type":"application/json;charset=UTF-8","content-length":"310","connection":"close","cache-control":"no-store"}
BODY: {"fieldErrors":{"":[{"code":"[invalidJSON]","message":"Invalid JSON in the request body. The property was []. The error was [Possible conversion error]. The detailed exception was [No content to map due to end-of-input\n at [Source: (org.apache.catalina.connector.CoyoteInputStream); line: 1, column: 0]]."}]}}
Response ended!

Also, using curl would return the desired result:

   'https://s5stratos-dev.fusionauth.io/api/user?email=<USER_EMAIL>'

will return:

{"user":{"active":true,"connectorId":"e3306678-a53a-4964-9040-1c96f36dda72","email":"USER_EMAIL","encryptionScheme":"salted-pbkdf2-hmac-sha256","id":"USER_ID","insertInstant":1657571797768,"lastLoginInstant":1657571797768,"lastUpdateInstant":1657571797768,"passwordChangeRequired":false,"passwordLastUpdateInstant":1657571797823,"tenantId":"SOME_ID","twoFactor":{},"usernameStatus":"ACTIVE","verified":true}}

I tried some other variations of the code above with no luck.
I hope I posted every thing needed and thanks in advance.

@dan Oops! thank you so much Dan, it worked as a charm. I was fooled into leaving this header in because I tried the exact same request setup using one of these free api endpoints instead of fusionauth api and it worked with the content-type included. Thanks again
