Unexpected error occurred on server when saving service

[seanccc]

Hi ,

I often get the error "Unexpected error occured on server" when saving service.  I cannot save service anymore as long as the error occurs ,  I have to exit the Edit mode and edit the service again. Even though, the 2nd editing won't assure the save can be successful.  

I don't see any related logs when the error occurs, including Thingworx platform logs and tomcat logs.  It's very boring especially when it happens more than 10 times in one hour sometimes.   

Any suggestion ?

I've been getting this error consistently in TWX 8.5.4. I get it for both services and mashups.  When it happens on a mashup the following is generated in the application log:

org.json.JSONException: JSONArray[0] not a string.

I have a mashup property with a hard coded value.  I'm trying to remove that hard coded value, but when I save, I get the error.
