Argument #2 must be of type array, null given

Problem/Motivation

Once I installed that module and navigate to : /admin/config/system/dbtable

I was able to add new table (manually created in database), however when I click on Table name I am getting following error:

The website encountered an unexpected error. Try again later.

TypeError: array_merge(): <strong>Argument #2 must be of type array, null given in array_merge() </strong>(line 40 of modules\contrib\custom_table_operations\src\Controller\TableContentController.php).

Also when I click Edit : I am getting following warning:

I created table in db using following sql (if needed the same) :

CREATE TABLE People (
    ID INT NOT NULL AUTO_INCREMENT,
    Name VARCHAR(50) NOT NULL,
    Surname VARCHAR(50) NOT NULL,
    Address VARCHAR(100),
    PRIMARY KEY (ID)
);

INSERT INTO People (Name, Surname, Address) VALUES
('John', 'Doe', '123 Main St, Anytown, USA'),
('Jane', 'Smith', '456 Oak St, Somecity, USA'),
('Michael', 'Brown', '789 Pine St, Thistown, USA'),
('Emily', 'Davis', '101 Maple St, Thattown, USA'),
('Daniel', 'Wilson', '202 Birch St, Anothertown, USA'),
('Emma', 'Taylor', '303 Elm St, Newcity, USA'),
('James', 'Anderson', '404 Cedar St, Oldtown, USA'),
('Olivia', 'Thomas', '505 Aspen St, Westcity, USA'),
('William', 'Johnson', '606 Cherry St, Eastcity, USA'),
('Sophia', 'Martinez', '707 Walnut St, Northcity, USA');

I am using Drupal 10.4 and PHP 8.126
