Parent node not found&&The parent reference for is invalid

[Zyf123456Zyf]

when i create a server via open62541,i can't load the xml correctly,just use the example you provide,such as“Opc.Ua.Di.NodeSet2.xml”
open62541(v1.3.15)
nodeset-loader(v0.5.0)

int main(int argc, const char *argv[]) {
UA_Server *server = UA_Server_new();
UA_ServerConfig_setDefault(UA_Server_getConfig(server));

if(!NodesetLoader_loadFile(server, "../nodeset/Opc.Ua.Di.NodeSet2.xml", NULL))
{
    UA_LOG_INFO(UA_Log_Stdout, UA_LOGCATEGORY_USERLAND, "importing the xml nodeset failed");
}
UA_StatusCode retval = UA_Server_run(server, &running);
//NodesetLoader is allocating memory for custom dataTypes, user has to manually clean up
// cleanupCustomTypes(UA_Server_getConfig(server)->customDataTypes);
UA_Server_delete(server);
return retval == UA_STATUSCODE_GOOD ? EXIT_SUCCESS : EXIT_FAILURE;

}

and the error print：

(ps:i can not upload imagine so just copy the print)

the server still run but can not load the whole xml,you know why?

I have a similar issue - the loader is throwing an assertion for some nodeset files.

I've tried to reproduce with the files from the distribution, but it is not a general problem: some nodesets load correctly:

• Opc.Ua.Di.NodeSet2.xml, Opc.Ua.Plc.NodeSet2.xml, testNodeset100nodes.xml and even the huge testNodeset.xml: load correctly
• Opc.Ua.NodeSet2.xml: failes with assertion assert(parentType) in the function SubtypeOfBase_init() (in file backends\open62541\src\DataTypeImporter.c). So I suspect this is only occuring for custom data types (function is called from DataTypeImporter_addCustomDataType())...

Did you find any solution? Maybe there was some progress, as I am at open62541 V1.4.14 and the file which failed for you works for me?

I was able to hunt it down to where the assert happens (and relate it to the nodeset file) - however, I am not sure, if this is incorrectly defined in the nodeset file or if the loader is not handling this case.

Here is a screenshot from Visual Studio debugging the open62514/examples/server_nodeset_loader.c with the Opc.Ua.NodeSet2.xml sample file:

I am not sure, if I am interpreting this correctly, but it seems like the <UADataType> definition for "Number" is using the numeric node id = 26 and also has a parent node id = 26 - which is (from my limited understanding how this works) wrong.

The other three files in the sample nodesets don't define the Number datatype, but only define an Alias for the same. So I am wondering, if the sample data file is the reason for the assertion (defining i=26 twice)?
