Youtube API - The request metadata specifies an invalid video description

Question

I know this question is duplcated, but the phenomena is different.

I use Youtube API PHP to upload my videos. Unfortunately, its caught errors:

{
    "status": "fail",
    "mess": "Failed to start the resumable upload (HTTP 400: youtube.video, The request metadata specifies an invalid video description.)"
}

I checked the description. Use mb_strlen() return result less than 5000 characters.

$title = mb_substr($title, 0, 100);
$description = mb_substr($description , 0, 4999);
$tags = array_slice($tags, 0, 15);

$snippet = new Google_Service_YouTube_VideoSnippet();
$snippet->setTitle($title);
$snippet->setDescription($description);
$snippet->setTags($tags);
$snippet->setCategoryId("22");

$status = new Google_Service_YouTube_VideoStatus();
$status->privacyStatus = "public";

$video = new Google_Service_YouTube_Video();
$video->setSnippet($snippet);
$video->setStatus($status);

Have some special characters exist: <>, |, ' (single qoute), (), ?, " (double quote).
I researched about this error, but not any results :(

Answer 1

You need to remove all < > characters from your description.

$description = str_replace(['>', '<'], '', $description);
$snippet->setDescription($description);
