elasticsearch-dump: illegal_argument_exception: [routing] is missing for join field [joinField]

• ElasticDump version: 3.3.19
• Elasticsearch version: 6.3.0
• Node.js version (note that nodejs v8+ is required for this tool): v9.11.2
• Full command you are having issue with (with inputs and outputs)

Exporting to file (works):

#!/usr/bin/env bash
elasticdump \
  --input=http://10.0.0.1:9200/index \
  --output=/data/index-mapping.json \
  --type=mapping

elasticdump \
  --input=http://10.0.0.1:9200/index \
  --output=/data/index-analyzer.json \
  --type=analyzer

elasticdump \
  --input=http://10.0.0.1:9200/index \
  --output=/data/index-data.json \
  --type=data

importing from file on another server (doesn’t work)

#!/usr/bin/env bash
elasticdump \
  --input=index-analyzer.json \
  --output=http://127.0.0.1:9200/index \
  --type=analyzer

elasticdump \
  --input=index-mapping.json \
  --output=http://127.0.0.1:9200/index \
  --type=mapping

elasticdump \
  --input=index-data.json \
  --output=http://127.0.0.1:9200/index \
  --type=data

It fails with:

{ _index: 'index',
  _type: 'doc',
  _id: 'article-112437',
  status: 400,
  error:
   { type: 'mapper_parsing_exception',
     reason: 'failed to parse',
     caused_by:
      { type: 'illegal_argument_exception',
        reason: '[routing] is missing for join field [joinField]' } } }

Currently working on a simple data set to reproduce.
