Description

A template like this

{scheme}://{host}:{port}/{path=**}?{**}

when matched with a URI like this

http://example.com/path?flag

and expanded with the same template will result a string like this

http://hortonworks.com:8888/top/mid/bot/file?flag=null&name=value

which is incorrect. The correct value should not contain =null and might look like this

http://hortonworks.com:8888/top/mid/bot/file?flag&name=value
