This is a very simplified version of code that I am using within our Customer 360 function to retrieve data from Jira. The code below works in 6.6 but fails with a 404 in 7.1. As far as I can tell so far, the issue has to do with how the curl command is encoding (or not?) some of the characters such as '+' and possibly '=':
The url_jira binding points to 'https://issues.couchbase.com/rest/api/latest/' and the above path is accessible without any authentication.
