Nodejs Sequelize.sync() hanging on SHOW INDEX? - node.js

Question

When restating our azure server the equalise.sync() method is hanging on the SHOW INDEX of a table it has just created. Even though the table is almost identical to one just created.
The model for our relation 'Teachers' is as follows:
'use strict';
module.exports = function(sequelize, DataTypes) {
var Teacher = sequelize.define('Teacher', {
email: DataTypes.STRING
} , {
classMethods: {
associate: function(models) {
// associations can be defined here
}
}
});
return Teacher;
};
And this is the code from a student relation that was successfully created, proceeds past SHOW INDEX and does not cause the script to hang:
'use strict';
module.exports = function(sequelize, DataTypes) {
var Student = sequelize.define('Student', {
email: DataTypes.STRING
}, {
classMethods: {
associate: function(models) {
// associations can be defined here
}
}
});
return Student;
};
And this is where the code gets up to before hanging/crashing:
