test_core.py is failing

[nafkhamdc]

We packaged this tool for GNU Guix, the reproducible package manager, but encountered a failure in the TestMofaModelMethods.test_get_methods test case when running the tests for the mofax project. The test is failing with an error in the get_data() method of the mofax/core.py module.

The test fails with the following error message:
