Description
Describe the bug
Formula property otherCount defined with EntitySchema as follows:
export const schema = new EntitySchema({
name: "MyEntity",
class: MyEntity,
properties: {
_id: { primary: true, type: 'number'},
other: { type: 'OtherEntity', reference: ReferenceType.MANY_TO_MANY},
otherCount: { formula: 'COUNT(other)' },
},
});Throws a TypeError: Cannot read properties of undefined (reading 'toLowerCase')

To Reproduce
Steps to reproduce the behavior:
- Define an entity in Javascript using the EntitySchema
- Add a property that is a formula without a type
- Error
Expected behavior
Formula properties should not need a type, as the docs show:
properties: {
objectVolume: { formula: 'obj_length * obj_height * obj_width' },
},
