Linkedin Video api upload throwing error 500 - php

Question

I am trying to create Video ad Campaigns using LinkedIn API. I am using Laravel, Guzzle and I have followed steps given in documentation to upload video
Initialize Upload for Video
Upload the Video
Finalize Video Upload
On Initialization I receive success response with multiple upload Urls depending on the file size. Using these uploadUrl I am making request to upload the file chunk using Guzzle but in response it is throwing INternal server error 500. I understand it can be server error but not sure if that raised to any header, param or token.
Please help If anyone has faced similar issue and got resolved. I am sharing the response of the initialize upload and request being made using Guzzle.

Calling Upload Urls

Answer 1

This worked for me.
$fileHandler = fopen(storage_path('app') . '/' . $fileName, 'r');
$client = new Client();
$uploadPartIds = [];
foreach ($uploadInstructions as $instruction) {
$chunkedUpload = $client->put($instruction->uploadUrl, [
'headers' => [
'Content-Type' => 'application/octet-stream',
'Authorization' => 'Bearer ' . $this->accessToken,
'LinkedIn-Version' => config('services.linkedIn.version'),
],
'body' => fread($fileHandler, $instruction->lastByte - $instruction->firstByte),
]);
//Push etag
$uploadPartIds[] = $chunkedUpload->getHeader('ETag')[0];
info($uploadPartIds);
}
return $uploadPartIds;
