Hello,

I'm running FinalBuilder Server v7.0.0.292 and can no longer access the web-services as they now throw an exception every time we access them.

They were previously working until I had to restart the machine because Finalbuilder Server refused to start any builds (and I could not bring the build service back up after stopping it).

Finalbuilder Server seems to be running fine but when I access the web services I get the following error message:

System.Runtime.Serialization.SerializationException: Type 'System.ServiceModel.ExceptionDetail' in Assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.

We are using the web-services to populate our custom dashboard (using the 'GetProjects' webservice method).

Thanks.

Hi Simon   
  
 Have a look in the windows eventlog, there must be something else happening, I don;t think this is the real exception. Has anything changed on your machine?

Hi Vincent,

The exceptions definitely real and I can reproduce it through a browser talking directly to the webservices (through Services/Finalbuilderserver.asmx).

Upon further testing I found that if I leave the authentication token blank then it works. This is the&nbsp;opposite&nbsp;of what I had found before resetting the machine (and our dashboard had been working for over a week passing a non-null authentication token). So, yeah, wierd! (and kind of annoying).

Thanks,

Simon. K
