NullPointerException in the Flow Designer (Data Stream Action)

[nachosg7]

Hello.

I am building an application to import the relationships between computers and software packages from a third-party application. I am using the flow designer (data stream action) to do it, but I am having some issues. When I test the data stream action, I obtain the next error:

Flow Designer: Operation(Rel. Computer-Software.TestDataStream) failed with error: java.lang.NullPointerException

Any idea to solve this? Previously, I have imported computers and software using the same way and it is working properly.

In case anyone is interested, I have solved this issue. The problem was in the name. I have called my Stream Data Action "Rel. Computer-Software". I have changed this name and the action is working properly.

Same problem with the name of the Data Stream Action Name which contains dot (Orion.VIM.VCenter), removing them solve the problem!
