The method getValue() does not exist on yii\db\ExpressionInterface. It seems like you code against a sub-type of yii\db\ExpressionInterface such as yii\db\JsonExpression or yii\db\Query or yii\db\ArrayExpression or yii\db\PdoValue or yii\db\Expression or yii\db\conditions\BetweenColumnsCondition or yii\db\conditions\SimpleCondition.

        if ($value instanceof Query) {
            list ($sql, $params) = $this->queryBuilder->build($value, $params);
            return "($sql)";
        }

        $placeholder = static::PARAM_PREFIX . count($params);
        $params[$placeholder] = Json::encode($value);

        return "CAST($placeholder AS JSON)";
    }
}
