“report.CRITICAL: Unable to serialize value. Error: Malformed UTF-8 characters, possible incorrectly encoded.”<\/p>\n

Please follow the steps to resolve this issue.<\/p>\n

1. Create registration.php file at below Path<\/strong><\/h4>\n

Path: app\/code\/<vendor>\/<yourmodule><\/strong><\/p>\n

<?php\r\n\\Magento\\Framework\\Component\\ComponentRegistrar::register(\r\n\\Magento\\Framework\\Component\\ComponentRegistrar::MODULE,\r\n'<vendor>_<yourmodule>',\r\n__DIR__\r\n);\r\n<\/pre>\n
2. Create module.xml file at below path<\/strong><\/h4>\n
Path: app\/code\/<vendor>\/<yourmodule>\/etc<\/strong><\/p>\n
<?xml version=\"1.0\" ?>\r\n<config xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\" xsi:noNamespaceSchemaLocation=\"urn:magento:framework:Module\/etc\/module.xsd\">\r\n<module name=\"<vendor>_<yourmodule>\" setup_version=\"1.0.0\">\r\n<sequence>\r\n<module name=\"Magento_Framework\"\/>\r\n<\/sequence>\r\n<\/module>\r\n<\/config>\r\n<\/pre>\n
3. Create di.xml file at below path<\/strong><\/h4>\n
Path: app\/code\/<vendor>\/<yourmodule>\/etc<\/strong><\/p>\n
<?xml version=\"1.0\" ?>\r\n<config xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\" xsi:noNamespaceSchemaLocation=\"urn:magento:framework:ObjectManager\/etc\/config.xsd\">\r\n<preference for=\"Magento\\Framework\\Serialize\\Serializer\\Json\" type=\"<vendor>\\<yourmodule>\\Rewrite\\Magento\\Framework\\Serialize\\Serializer\\Json\"\/>\r\n<preference for=\"Magento\\Framework\\Serialize\\Serializer\\JsonHexTag\" type=\"<vendor>\\<yourmodule>\\Rewrite\\Magento\\Framework\\Serialize\\Serializer\\JsonHexTag\"\/>\r\n<\/config>\r\n<\/pre>\n
4. Create Json.php file at below path<\/strong><\/h4>\n
Path: app\/code\/<vendor>\/<yourmodule>\/Rewrite\/Magento\/Framework\/Serialize\/Serializer<\/strong><\/p>\n
<?php\r\n\r\nnamespace <vendor>\\<yourmodule>\\Rewrite\\Magento\\Framework\\Serialize\\Serializer;\r\n\r\nclass Json extends \\Magento\\Framework\\Serialize\\Serializer\\Json\r\n{\r\npublic function utf8ize($mixed)\r\n{\r\nif (is_array($mixed)) {\r\nforeach ($mixed as $key => $value) {\r\n$mixed[$key] = $this->utf8ize($value);\r\n}\r\n} elseif (is_string($mixed)) {\r\nreturn mb_convert_encoding($mixed, \"UTF-8\", \"UTF-8\");\r\n}\r\n\r\nreturn $mixed;\r\n}\r\n\/**\r\n* @inheritDoc\r\n* @since 101.0.0\r\n*\/\r\npublic function serialize($data)\r\n{\r\n$result = json_encode($this->utf8ize($data));\r\nif (false === $result) {\r\nthrow new \\InvalidArgumentException(\"Unable to serialize value. Error: \" . json_last_error_msg());\r\n}\r\nreturn $result;\r\n}\r\n\r\n\/**\r\n* @inheritDoc\r\n* @since 101.0.0\r\n*\/\r\npublic function unserialize($string)\r\n{\r\n$result = json_decode($string, true);\r\nif (json_last_error() !== JSON_ERROR_NONE) {\r\nthrow new \\InvalidArgumentException(\"Unable to unserialize value. Error: \" . json_last_error_msg());\r\n}\r\nreturn $result;\r\n}\r\n}<\/pre>\n
5. Create JsonHexTag.php file at below path<\/strong><\/h4>\n
Path: app\/code\/<vendor>\/<yourmodule>\/Rewrite\/Magento\/Framework\/Serialize\/Serializer<\/strong><\/p>\n
<?php\r\n\r\nnamespace <vendor>\\<yourmodule>\\Rewrite\\Magento\\Framework\\Serialize\\Serializer;\r\n\r\nclass JsonHexTag extends \\Magento\\Framework\\Serialize\\Serializer\\JsonHexTag\r\n{\r\n\/**\r\n* @inheritDoc\r\n* @since 102.0.1\r\n*\/\r\npublic function serialize($data): string\r\n{\r\n$data = $this->utf8convert($data);\r\n$result = json_encode($data, JSON_HEX_TAG);\r\nif (false === $result) {\r\nthrow new \\InvalidArgumentException('Unable to serialize value.');\r\n}\r\nreturn $result;\r\n}\r\n\r\npublic function utf8convert($mixed, $key = null)\r\n{\r\nif (is_array($mixed)) {\r\nforeach ($mixed as $key => $value) {\r\n$mixed[$key] = $this->utf8convert($value, $key);\r\n}\r\n} elseif (is_string($mixed)) {\r\n$fixed = mb_convert_encoding($mixed, \"UTF-8\", \"UTF-8\");\r\nreturn $fixed;\r\n}\r\nreturn $mixed;\r\n}\r\n}\r\n<\/pre>\n
That’s it.<\/p>\n
