Magento Upgrade: Troubleshooting ValueError in Magento 2.4.5

Upgrading to the latest version of Magento can be a daunting task, especially when encountering errors that seem to appear out of nowhere. In this article, we will delve into the issue of ValueError: setcookie(): "path" option cannot contain ",", ";", " ", "\t", "\r", "\n", "\013", or "\014" in PhpCookieManager.php:152 that occurs in Magento 2.4.5 after a version upgrade. We will explore the possible causes, provide solutions, and offer best practices to prevent such errors in the future.

The error message ValueError: setcookie(): "path" option cannot contain ",", ";", " ", "\t", "\r", "\n", "\013", or "\014" in PhpCookieManager.php:152 indicates that there is an issue with the path option in the setcookie() function. This function is used to set cookies in the browser, and the path option specifies the directory where the cookie is accessible.

The error occurs because the path option contains one or more of the following characters:

, (comma)
; (semicolon)
(space)
\t (tab)
\r (carriage return)
\n (newline)
\013 (line feed)
\014 (form feed)

These characters are not allowed in the path option, and the setcookie() function throws a ValueError exception when it encounters them.
