The "asynchronous script timeout" error in Protractor typically occurs when a browser command, such as browser.get(), takes too long to execute. This error is usually due to a slow network or server response or some other issue that prevents Protractor from loading the page in a timely manner.

To fix this issue, you can try the following solutions:

  1. Increase allScriptsTimeout: Protractor has a default timeout for script execution called allScriptsTimeout. You can increase this timeout in your Protractor configuration file (protractor.conf.js or conf.js).

    exports.config = { // Other configurations... allScriptsTimeout: 30000, // Set a higher value, e.g., 30 seconds };

    By increasing allScriptsTimeout, you allow more time for the browser.get() command to complete before triggering a timeout error.

  2. Add a Wait Condition: Instead of increasing the timeout globally, you can add a wait condition before browser.get() to ensure the page is fully loaded before proceeding.

    Protractor provides browser.wait() for handling asynchronous operations. You can use this function along with Expected Conditions to wait for elements to be present, visible, or other conditions before navigating to the page.

    For example, you can wait for an element to be present before calling browser.get():

    const EC = protractor.ExpectedConditions; const desiredElement = element(by.css('selector-for-element')); // Wait for the element to be present browser.wait(EC.presenceOf(desiredElement), 10000); // Wait for 10 seconds // Proceed with browser.get() after the element is present browser.get('');
  3. Check Network or Server Performance: If the issue persists, it could be due to slow network or server response times. Make sure that the network connection and the server hosting the application are performing well. Check for any network-related issues that could be causing delays in loading the page.

  4. Check the URL: Ensure that the URL provided to browser.get() is correct and that it leads to the expected page. Incorrect or invalid URLs can cause the browser to hang and trigger a timeout.

By using one or a combination of these solutions, you can address the "asynchronous script timeout" error and ensure that browser.get() executes successfully in Protractor. If the issue persists, consider reviewing the application's performance and network conditions to identify any potential bottlenecks.
