CypressError: Timed out retrying after 4000ms

A Cypress command timed out while retrying. Cypress automatically retries assertions until the timeout, then fails. The default is 4 seconds.

Common Causes

  1. 1Element takes longer than 4 seconds to appear
  2. 2Selector does not match any elements
  3. 3Element is hidden or covered by another element
  4. 4Asynchronous data hasn't loaded yet
  5. 5Component hasn't finished rendering

How to Fix

Increase timeout for specific command

cy.get('#element', { timeout: 10000 }).should('be.visible');

Override the default 4-second timeout for this specific command.

Increase global default timeout

// cypress.config.ts
export default defineConfig({
  defaultCommandTimeout: 10000,
});

Sets the default timeout for all cy commands globally.
