S3 putObject puts object into folder for some reason

Verified on: Node.js: 6.10.0, 8.9.3, 10.11.0 aws-sdk: 2.373.0, 2.360.0 ubuntu 16.04

Code:

const aws = require('aws-sdk');
const s3 = new aws.S3();
const fs = require('fs');
const fileData = fs.readFileSync('./tmp/d');
const Key = 'dkoker';
s3.putObject({
  Bucket: 'dkoker-test',
  Body: fileData,
  Key,
}).promise().then(() => console.log('Object recorded')).catch(e => console.log(e));

Issue description: Put object operation puts object into a folder with bucket name if bucket name contains Key value.

• The result of this operation is the following: bucket dkoker-test has a folder dkoker-test with a file dkoker inside.
• The expected result: dkoker file lays inside bucket, no nested folders should exist

In example above: bucket name is dkoker-test (disregard what it means). Name of file is dkoker starts with the same characters as name of bucket: dkoker-test. Here is the list of tested Key values:

• dkoker
• dkoke
• dkok
• d For all of them an intermediate folder was introduced for some reason Once I’ve changed Key value to m, everything worked as expected
