Sequelize and NOT operator

Hi all,I have to run this by the community to check whether this is an issue with my code, or with sequelize.I have to transform a SQL-like filter into a sequelize filter object. The translation is for the most part correct, however, one thing I ran into is a peculiar behaviour of sequelize when it encounters [Op.not] in the filter object.The filter in question looks something like: 'condition_a AND NOT(condition_b OR condition_c). When translated to sequelize object, it looks like this:{ jsonField: { [Op.and]: [ condition_a, [Op.not]: { [Op.or]: [ condition_b, condition_c ] } ] }} However, when inspecting the generated query, it appears as if the [Op.not] contents are ignored, i.e. the filter is 'condition_a AND jsonField != {}'.Am I incorrectly using the Op.not symbol, or is there a known issue with it wrapping other filters?
