Could not resolve the JSON path

[IvanDrag0]

I've compiled the program from source and trying to load the following JSON:

https://raw.githubusercontent.com/usnistgov/oscal-content/master/examples/ssp/json/ssp-example.json

With the following Schema:

https://raw.githubusercontent.com/usnistgov/OSCAL/main/json/schema/oscal_ssp_schema.json

When I load the files, I get the following error in the compiler:

"Could not resolve the JSON path '#assembly_oscal-ssp_system-security-plan' within the file path '<PATH>'."

And then this error comes up when I continue execution:

I've checked the JSON against the schema and it validates correctly.
