A few notes you might consider, based on your written code on the <form>...</form> part:
First of all, the <form>...</form> element is required to collect all user input data, regardless of the type of user input entry (e.g., radio buttons, checkboxes, text bar); the data collected is submitted to the URL specified in the action attribute; you may add the attribute target with a value “_blank”;
For this challenge, to submit for instance, a cat photo URL, you need to create a Submit button using the <button>...</button>, so that the data entered in the text bar could be collected as a ‘form data’ and submitted to the form’s specified URL; the button must have the attributes type and value, and the button name specified like ‘Submit’ or ‘Go’ as an example; the value attribute is important so that it would be recognized as a ‘submit’ form of data and not default to a mere ‘on-off’ switch; lastly remove the forward slash before https, as I’ve noticed.
If you read the failing message it tells you what is incorrect. It says
Your form should have an actionattribute which is set to https://www.freecatphotoapp.com/submit-cat-photo
Your action attribute is set to /https://www.freecatphotoapp.com/submit-cat-photo
