Confluence does not load Open API's

[Deleted user]

I was using Open API's to show swagger and it was working as expected, not sure but suddenly getting the below errors in web (using chrome Browser)

1/  "Refused to apply style from 'https://confluence-open-api.herokuapp.com/vendor-b64c7d.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled."

2/ jquery.js:2580 Error while parsing the 'sandbox' attribute: 'allow-storage-access-by-user-activation' is an invalid sandbox flag.

3/ GET https://confluence-open-api.herokuapp.com/vendor-b64c7d.js net::ERR_ABORTED 404 (Not Found)

We are the vendors for Open API Documentation for Confluence, and sorry to hear that you are experiencing difficulties with the app.

The two assets that you mentioned (vendor-b64c7d.css and vendor-b64c7d.js) are from an earlier release of our app; so it may be the case that your browser has cached an older copy of the app's HTML template.

Recommend that you clear your browser's cache and try again, or try refreshing the page without cache using CTRL+F5 or CTRL+SHIFT+R (Windows/Linux) or CMD+SHIFT+R (Mac)

For reference, the current asset versions (as at July 3, 2020) are vendor-21c04f-{css,js}.

Hope this helps.
