It's possible that the pages are being restricted because of other issues on your website if the pages aren't specifically blocked in the robots.txt file. For instance, the noindex tag or a rel="canonical" element that directs users to another URL can forbid the pages. By analyzing the source code of your website and verifying sure there are no tags stopping Google from crawling and indexing the pages, you may look for these problems.

In the specific example you provided, the URL contains a script file which is likely being blocked by the robots.txt file. You should check the rules in the robots.txt file to make sure that this file is not being blocked.
