Hi,

It's not very clear what is causing the issue, could you mention which version are you using ? also verify the correct dependencies in place.

I am using the latest version of lightcouch, with gson 2.2, httpclient 4.2.2. When I instantiat the couchdbclient object the error in the stack trace appears. It looks like their is nothing in the http entity object. Should it be that way? Does LightCouch add junk data or something when connecting to couchdb?

Looking into that again, it seems to fail due to an error returned from CouchDB on the head request, can you see what is happening on the DB logs ?

also try with setting createDbIfNotExist to false.

I had the same problem, I set createDbIfNotExist to false; then it gave out "Authentication Error".

I put a username and password on couchdb and it worked fine.

Then I changed the createDbIfNotExist to true and it works.
