Content-Type not right

[aqr199]

1. Content-Type not right

src/Oracle/Oci/ObjectStorage/ObjectStorageClient.php

line 2673

$__headers = ['Content-Type' => 'application/json', 'User-Agent' => UserAgent::getUserAgent()];

upload image Content-Type always application/json

change $__headers

$__headers = ['User-Agent' => UserAgent::getUserAgent()];

now upload image Content-Type: image/jpeg

How to ensure the Content-Type is correct?
Modify the source code or have other settings

2. How does it work?

src/Oracle/Oci/ObjectStorage/ObjectStorageClient.php
line 2692

if ($contentType != null) {
HttpUtils::addToArray($__headers, "contentType", HttpUtils::attemptEncodeParam($contentType));
}
