Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value:

[Geoff]

I'm getting the below error from json.net when storing my model:

System.InvalidOperationException was unhandled by user code

My code in the api controller post method is small:

public HttpResponseMessage<UserDataModel> Post(UserDataModel
model)
{
if (null == model) return new
HttpResponseMessage<UserDataModel>(HttpStatusCode.BadRequest);
Session.Store(model);
return new
HttpResponseMessage<UserDataModel>(HttpStatusCode.OK);
}

The model just has a few basic string properties. Ideas? Thanks!

Are the client and server of the same version?

[Justin A]

I get this error when my website code is using v888 RavenDb.Client .. from nuget 

but the server is using v701.

[mvmv]

same here, I guess client and server need to be in same version?

[Oren Eini (Ayende Rahien)]

Yes, they need to.

Or, you can upgrade to 911 and use store.JsonRequestFactory.DisableHttpCompressiong = true;

Sorry, I thought I had email updates turned on, just saw these
messages.

Yeah it looks like I'm using RavenDB.Client 1.0.888 and seem to
remember version 800 on the server. For some reason the big font and
bold formatting on build 888 my eyes totally missed and treated it as
a header. Maybe a heading "Older versions" above everything else will
help idiots like me rushing through the server install :).

I'll try 888 on the server and report back. Right now our server
doesn't have any data in it but what is the recommendation on
upgrading the server? Should I stop the service (assuming uninstall
does), Raven.Server.exe /uninstall, delete everything, copy latest
over and restore any config changes (port etc.)? Once it has data I'm
assuming I'd add backup the Server\Data directory and restore it?

Upgrading to 888 on the server fixed the issue. Thanks; will be sure
to keep these in sync going forward.

As to the upgrade process I did notice some updating related
powershell scripts though I wasn't sure if that was just for plugins
or not. Suppose it would be easy enough to write a powershell script
to do some of the server upgrade work.

[Itamar Syn-Hershko]

Powershell won't cut it, in 1.2 we will introduce a proper automated way to do updates

The current scripts are for upgrading the bundles
