`e.failures is not iterable` when trying to access failures

superstruct version: 0.10.11 node version: 12.17.0

I’m struggling to access failures and hoping someone here could help out…

const { object, assert, string } = require('superstruct');

const User = object({
  firstName: string(),
  lastName: string()
});

try {
  assert({}, User);
} catch (e) {
  for (const failure of e.failures) {
    console.log('failure', failure);
  }
}

Result: TypeError: e.failures is not iterable

How can I get an actual array of failures? It looks like it’s a generator of some sorts.

Uhoh, sounds like a bug. Can one of you open another issue for it and I’ll check it out? Thanks!

const User = object({
  firstName: string(),
  lastName: string()
});

try {
  assert({}, User);
} catch (e) {
  for (const failure of e.failures()) {
    console.log('failure', failure);
  }
}
// output 
 failure {
    value: undefined,
    type: 'string',
    path: [ 'firstName' ],
    branch: [ {}, undefined ]
  }
 but I want to get `firstName` and `lastName`  fields.
