I'm trying out

n/query

and I'm trying to join journal entry lines with matching credit memos based on the "entity" field in each. It's giving me the following error

You have entered an invalid type argument: options.fieldId

. Any ideas what I'm doing wrong?

var jeQuery = query.create({ type: 'transaction' });
        var entityJoin = jeQuery.joinFrom({ name: 'entity', source: 'transaction' });
