knex no longer spyable by jest ?

Environment

Knex version: 0.20.11 OS: macos

Bug

When updating from 0.20.10 to 0.20.11, test suite breaks because Jest spies cannot be applied. For example, jest.spyOn(db, 'destroy') or jest.spyOn(db, 'transaction') throw the following error :

TypeError: Cannot assign to read only property 'transaction' of function 'function knex(tableName, options) {
        return createQueryBuilder(knex.context, tableName, options);
      }'

Is this intentional ? Is there a new way of doing things to get around this problem ? I’d be happy o provide additional information if needed
