Problem

Navigating to a repository page shows "We couldn't find the page you requested" error popup

The following appears in the the browser developer tools console

Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-2uOQtIsVzHr1u4XAN96+tcBOqQIM9wp6kovH43HGcfs='), or a nonce ('nonce-...') is required to enable inline execution.

Also, below in the reponse

{"message":"null for uri: https://URL/rest/api/1.0/projects/<PROJECT KEY>/repos/<reposlug>/undefined/rest/jira-integration/latest/servers","status-code":404}

Diagnosis

Environment

• This issue reproducible in Chrome and not in IE

• A proxy like F5, nginx, HAproxy  and Apache infront of Bitbucket

Cause

We have noticed this when the extra Content Security Policy CSP headers are set in the proxy.

e.g. 

Content-Security-Policy:script-src 'self'; object-src 'self' 

Resolution

1. Remove the Content Security Policy settings from proxy
2. Stop the atlbitbucket service, rename the application-data/plugins/.osgi-cache/felix directory to felix.bkp and then restart the service.
