SYMPTOM

You get this exception in the ErrorLog when fetching track data using SOAP:

HttpCall failed: http://localhost:8090/api/messageStore/list/2716206 | System.TypeInitializationException: The type initializer for 'GpsGate.Online.Message.v7.DAO.GateMessageReaderDAOV7' threw an exception. ---> System.TypeInitializationException: The type initializer for 'com.gpsgate.avro.messages.GateMessageData' threw an exception. ---> System.IO.FileLoadException: Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies.

SOLUTION

The best long-term solution is to switch to using REST instead.

Until you have switched to REST, please edit web.config which you find under C:\GpsGateServer\IIS. And add the following inside the <configuration> tag.

 
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="10.0.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
