I have a webservice where I’m sending some data. The return of the service is returning me this message below, in the integration manual, says it would be an internal error, wanted to understand if the problem is on my side or the service provided.

Your client is written in C#. So there is no way java.lang.NullPointerException on your side. Because as the name of this exception already says, it is a Java exception.

It may even be that you invoked their service with some invalid data or parameter, but even then, it’s still their mistake anyway. 99% of the time, have a NullPointerException being spat out is a programming error. In the other 1% is a sign that the code is a very badly done gambiarra without any kind of decent error handling. In this case, the component from which this error came is their server, and so that’s where the error is.
