I solve this issue by flushing my Redis Cache from by running following commands

redis-cli 
flushall

I hope this works.

EDIT

  • I am about redis-cli flushall commands. Why because, when we run these commands, it shows not defined command

Go to this file location and paste below code and best way try to override this file : /vendor/magento/framework/Serialize/Serializer/Json.php

public function utf8ize( $mixed ) {
    if (is_array($mixed)) foreach ($mixed as $key => $value) $mixed[$key] = $this->utf8ize($value);
    elseif (is_string($mixed)) return mb_convert_encoding($mixed, "UTF-8", "UTF-8");
    return $mixed;
}

public function serialize($data){
    $result = json_encode( $this->utf8ize( $data ) );
    if (false === $result) {
        throw new \InvalidArgumentException("Unable to serialize value. Error: " . json_last_error_msg());
    }
    return $result;
}

How to override this file

The preference for the SerializerInterface was added since 2.2.x version of the Magento, and declared in the app/etc/di.xml:

<preference for="Magento\Framework\Serialize\SerializerInterface" type="Magento\Framework\Serialize\Serializer\Json" />

Override Hint

Then create the class [Vendor][Module]\Serialize\Serializer\Json that extends Magento\Framework\Serialize\Serializer\Json and make your changes in there.

Refer this article to solve out an issue

This error means that you don't have enough space in the MySql column "params", of the table "#__extensions", to save all the required parameters that the Cookies Policy Notification Bar needs, and the json data breaks during saving the data.

change the type of the column "params" from "TEXT" to "LONGTEXT" enter image description here
