CypressError: element has been detached from the DOM

The element that Cypress was interacting with was removed from the DOM and re-rendered. This is common in React/Vue/Angular apps where components re-render.

Common Causes

  1. 1React state update caused a re-render between finding and clicking the element
  2. 2List items were re-ordered
  3. 3Component was unmounted and remounted
  4. 4Navigation removed and recreated the element

How to Fix

Re-query the element before interacting

// Instead of storing the element:
// const el = cy.get('#item');
// el.click();

// Always re-query:
cy.get('#item').click();

Cypress automatically retries the query. Avoid storing element references in variables.

Use .should() to wait for stability

cy.get('[data-testid="list-item"]')
  .should('have.length', 5)
  .first()
  .click();

Assert on the list stability before interacting with individual items.
