Sample Error report:

This report details a list of JavaScript errors encountered, their frequency, and potential causes. Understanding and addressing these errors is crucial for ensuring the smooth functioning of a web application.

  1. Cannot set properties of null (setting ‘textContent’) – 7.73k occurrences: This error typically occurs when trying to access or modify a property of an element that doesn’t exist in the DOM. The use of document.querySelector might be returning null because the selector does not match any elements.
  2. null is not an object (evaluating ‘document.querySelector(…).textContent = ${precioActualizado.toFixed(2)} €‘) – 2.81k occurrences: Similar to the first error, this issue arises when the element targeted by document.querySelector is not found, resulting in null.
  3. ((ce.event.special[o.origType] || {}).handle || o.handler).apply is not a function – 1.95k occurrences: This error suggests a problem with an event handler in jQuery. It might be due to a mismatch between jQuery versions or improper use of event methods.
  4. Failed to execute ‘appendChild’ on ‘Node’: parameter 1 is not of type ‘Node’. – 1.52k occurrences: This error happens when the argument passed to appendChild is not a valid DOM node. This could be due to an incorrect reference or a null value.
  5. Cannot read properties of null (reading ‘remove’) – 533 occurrences: This error indicates an attempt to call the remove method on an element that doesn’t exist in the DOM.
  6. Argument 1 (‘node’) to Node.appendChild must be an instance of Node – 421 occurrences: Similar to the earlier appendChild error, this one also indicates that the argument passed is not a valid DOM node.
  7. Failed to execute ‘observe’ on ‘MutationObserver’: parameter 1 is not of type ‘Node’. – 319 occurrences: MutationObserver requires a DOM node to observe. This error suggests that the target element is not a valid node.
  8. null is not an object (evaluating ‘document.querySelector(…).remove’) – 178 occurrences: This is another instance of attempting to operate on a non-existent DOM element.
  9. Cannot read properties of undefined (reading ‘dispatchEvent’) – 103 occurrences: This error suggests an attempt to trigger an event on an undefined object.
  10. Argument 1 (‘target’) to MutationObserver.observe must be an instance of Node – 85 occurrences: Similar to the previous MutationObserver error, the target for observation is not a valid DOM node.
