Elasticsearch-js: Using apiVersion 5.x is broken since latest release

[JrSchild]

Since the last release of this module I am unable to use apiVersion 5.x. This still worked with the previous release. According to the documentation I would assume it should work.

Test code:

const elasticsearch = require('elasticsearch');

const client = new elasticsearch.Client({
  hosts: ['localhost:9200'],
  apiVersion: '5.x'
});

client.ping({
  requestTimeout: 1000
}, function (error) {
  if (error) {
    console.trace('elasticsearch cluster is down!');
  } else {
    console.log('All is well');
  }
});

The error is as follows:

TypeError: Cannot read property 'prototype' of undefined
    at Object.<anonymous> (.../node_modules/elasticsearch/src/lib/apis/5_x.js:4990:31)

FWIW, I'm having the same issue. Rolled back to 13.0.0 and the error is gone.

I have the same error with the latest version.

Thanks everyone, this was caused by the new ingest.processor.* api. The generator wasn't prepared to handle methods that had multiple path segments. Fixed in 629c7498ae51a7192595de0cb82bb77c0b0895cf and released in v13.1.1

@spalger - when I install the latest version 13.1.1 I get an unmet peer dependency on [email protected]

├── UNMET PEER DEPENDENCY [email protected]
└── [email protected]

I have [email protected] installed as a dev dependency. Shouldn't it be a dev dependency for elasticsearch?

@aleybovich pretty sure that's unrelated to elasticsearch-js, we don't depend on chai
