Make sure that the object you are selecting is draggable and droppable or not. I have written custom command like below. Please see f it works for you.

Cypress.Commands.add('dragAndDrop', (subject, target) => {
    Cypress.log({
        name: 'DRAGNDROP',
        message: `Dragging element ${subject} to ${target}`,
        consoleProps: () => {
            return {
                subject: subject,
                target: target
            };
        }
    });
    const BUTTON_INDEX = 0;
    const SLOPPY_CLICK_THRESHOLD = 10;
    cy.get(target)
        .first()
        .then(($target) => {
            let coordsDrop = $target[0].getBoundingClientRect();
            cy.get(subject)
                .first()
                .then((subject) => {
                    const coordsDrag = subject[0].getBoundingClientRect();
                    cy.wrap(subject)
                        .trigger('mousedown', {
                            button: BUTTON_INDEX,
                            clientX: coordsDrag.x,
                            clientY: coordsDrag.y,
                            force: true
                        })
                        .trigger('mousemove', {
                            button: BUTTON_INDEX,
                            clientX: coordsDrag.x + SLOPPY_CLICK_THRESHOLD,
                            clientY: coordsDrag.y,
                            force: true
                        });
                    cy.get('body')
                        .trigger('mousemove', {
                            button: BUTTON_INDEX,
                            clientX: coordsDrop.x,
                            clientY: coordsDrop.y,
                            force: true
                        })
                        .trigger('mouseup');
                });
        });
});
