Hi!
This is kind of frustrating problem happens in Jenkins UI in Jenkins course level 2. When you trying to to POST something on the server, like saving something in the form (install plugins, save button etc) the 403 error appears with the text:
HTTP ERROR 403 No valid crumb was included in the request, see screenshot attached
Is there anything I can do with to avoid this error?
The error message “HTTP ERROR 403 No valid crumb was included in the request” usually indicates a problem with Cross-Site Request Forgery (CSRF) protection in Jenkins. CSRF protection is intended to ensure that only forms that have been submitted from Jenkins itself will be accepted by the server. If the CSRF token (also known as a crumb) is not present or incorrect, Jenkins will reject the request with a 403 error.
If this is happening in KodeKloud Engineer try resetting the task.
