Using Exported Corpus from NLP.js-App within NLP.js

Summary

At the moment we're looking to make use of the NLP.js application (https://github.com/axa-group/nlp.js-app) to train our model via the interface and export it to JSON for external storage. Then, we hope to use this exported Corpus data within a separate NLP.js application (https://github.com/axa-group/nlp.js) to respond to the user(s).

However, we are having difficulty using the exported Corpus data within the separate NLP.js system. It appears that the exported data from the App uses "Brain" as the primary classifier, but when attempting to load this configuration into NLP.js it throws errors.

Simplest Example to Reproduce

const { NlpManager } = require('node-nlp');

const corpus = require('./neural-corpus.json');

(async () => {  
  const manager = new NlpManager({ useNeural: 'brain' });

  await manager.import(corpus);

  await manager.train();

  const response = await manager.nlp.process('en', 'Hello');

  console.log(JSON.stringify(response));
})();

Here is the supplied Corpus which was exported from the NLP.js-App (after training) using manager.export();:

neural-corpus copy.json.txt

Expected Behavior

The expected behaviour would be that we could train the data, export it and then use this exported model in the processor (NLP.js NlpManager).

Current Behavior

(node:11966) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'length' of undefined at NluManager.fromJSON (node_modules/@nlpjs/nlu/src/nlu-manager.js:351:38)

Possible Solution

If possible, could you supply us with the correct way to achieve this?
