Error -13000 occured at XNET IP Stack Create vi

Issue Details

When using the LabVIEW examples for XNET IP Stack, for example the NI-XNET IP Stack Simple UDP.lvproj (located in C:\Program Files\NI\LVAddons\nixnet\1\examples\nixnet\projects\NI-XNET Ethernet\IP Stack\NI-XNET IP Stack Simple UDP.lvproj), the XNET Example IP Stack Config - Single Interface vi generates a JSON configuration string to use with XNET IP Stack Create, which in turn creates the XNET IP Stack for use with TCP and/or UDP communication. LabVIEW might get the following error:

Error -13000 occured at XNET IP Stack Create.vi:890001

Possible reason(s):

An internal error occured in the NI-XNET IP Stack.
Contact National Instruments for support. 
 
How can I resolve this error?

Solution

It may be a mistake in the XNET IP Stack schema version of the JSON file, which can occur when having several versions of XNET and LabVIEW on the computer. The JSON that NI-XNET requires is governed by a schema that installs with the driver. The default installation location for this schema is %Public\Documents\National Instruments\NI-XNET\Documentation\xnetIpStackSchema-n.json, where n is a version number.

Check the JSON file version against the version of the JSON configuration in the path and verify they are the same by placing a probe or an indicator on the string output of the VI, and checking the JSON config version in the following path (). If not, change this manually.
