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

            return "($sql)" . $this->getTypecast($expression);
        }

        if ($value instanceof ArrayExpression) {
            $placeholder = 'array_to_json(' . $this->queryBuilder->buildExpression($value, $params) . ')';
        } else {
            $placeholder = $this->queryBuilder->bindParam(Json::encode($value), $params);
        }

        return $placeholder . $this->getTypecast($expression);
    }
