Looks like a permission error. Did you run it with medallion as the TAXII server? Did you use the configuration and data included with that project?

[IgorGanapolsky]

I just used the default config. I did not set up a separate TAXII server. Do I need to?

@IgorGanapolsky - yes you need to run a TAXII server if you want to use the TAXII data store.
See https://github.com/oasis-open/cti-taxii-server. You probably want to use the MemoryBackend
