Query checking for not-null

1

How do you ask for a value to be not null in a query?
This doesn’t’ work:
const aliasFilter = {
fields: {id},
where: {
name: { ilike: ‘%’ + value + ‘%’,
(this.businessObjectName + ‘id’): is not null
}
}

Dave says:
See these docs: Where filter | LoopBack Documentation
And try this format, with ‘neq’ for not equal
{blah:{neq:null}}
