I had a working standalone jar which updates an item via a REST call (openHAB 3.1.0.M2).
Since the update to openHAB 3.1.0.M4 I get a “HTTP 406 Not Acceptable” when I send the call.
Call from API Explorer (does work):
curl -X PUT "http://10.x.x.x:8080/rest/items/dingzButton3/state" -H "accept: */*" -H "Content-Type: text/plain" -H "Authorization: Bearer ..." -d "30"
I use the token created via GUI (and it has worked until M2).
If I change the token to something wrong I get an HTTP401 as expected.
