Hi, I'm having problems with updating expressions using REST. Non-updating queries execute fine without errors but when I use updating expressions the REST service returns a 400 (bad request) error. For instance: the following body of a POST request    <run xmlns='http://basex.org/rest'><text>insertDummy.xq</text></run> with code in file insertDummy.xq:    xquery version '3.0';    insert node <structure>nada</structure> into collection("component")/structures sent to:    http://admin:admin@localhost:8984/rest/component/ returns a "(400) Bad request" error while if I substitute the code in file insertDummy.xq for a non updating expression such as:    xquery version '3.0';    let $r := collection("component")/structures    return $r it works fine! I suspected this was a result of user rights so I added the admin credentials to the http path. No change, problem persists. Also, I de-installed the program, made sure all files were gone, and then re-installed the (win PC) program again to wipe any weird settings I may have changed. Still no luck... The above code did work on a previous installation (I beleive I was using 7.7.1). Any help would be highly appriciated. Many thanks, Fredrik Hedberg
