Description

A user reported hitting this error:

Applying migration pulp.server.db.migrations.0029_applicability_schema_change failed.

Halting migrations due to a migration failure.

I tested and couldn't reproduce. I think the difference might be mongo or pymongo versions. I was using:

python2-pymongo-gridfs-3.6.1-1.fc28.x86_64
python2-mongoengine-0.15.3-1.fc28.noarch
mongodb-server-3.6.6-1.fc28.x86_64
python2-pymongo-3.6.1-1.fc28.x86_64
mongodb-3.6.6-1.fc28.x86_64

The user was using:

python-pymongo-gridfs-3.2-2.el7.x86_64
python-pymongo-3.2-2.el7.x86_64
python-mongoengine-0.10.5-1.el7.noarch
mongodb-server-2.6.12-6.el7.x86_64

This patch seemed to fix the problem for the user:
