Elasticsearch - Reindex Picks Up No Documents using official documentation - elasticsearch

Question

I am following reindex documentation here: https://www.elastic.co/guide/en/cloud/current/ec-migrate-data.html
I have two Elasticsearch indexes in localhost:
192.168.0.100:9200
{
"name" : "fses01",
"cluster_name" : "fs-es-cluster",
"cluster_uuid" : "DqVDBBafRaO9UAJPKuc_xQ",
"version" : {
"number" : "7.14.0",
"build_flavor" : "default",
"build_type" : "docker",
"build_hash" : "dd5a0a2acaa2045ff9624f3729fc8a6f40835aa1",
"build_date" : "2021-07-29T20:49:32.864135063Z",
"build_snapshot" : false,
"lucene_version" : "8.9.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
With the following index:
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open formshare_records NpEFzsGvTEmivnYjJhwHJg 5 1 51343 0 7.8mb 3.9mb
192.168.0.100:9201
{
"name" : "es01",
"cluster_name" : "es-docker-cluster",
"cluster_uuid" : "bvsRXLwZRtKuWIrIuKx0hg",
"version" : {
"number" : "7.14.2",
"build_flavor" : "default",
"build_type" : "docker",
"build_hash" : "6bc13727ce758c0e943c3c21653b3da82f627f75",
"build_date" : "2021-09-15T10:18:09.722761972Z",
"build_snapshot" : false,
"lucene_version" : "8.9.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
With the same index but blank:
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
green open formshare_records uxvizIAIS82YBHSsvpq4-Q 5 1 0 0 2kb 1kb
I am doing a reindex using CULR with the following:
curl -X POST "192.168.0.100:9201/_reindex" -H 'Content-Type: application/json' -d'
{
"source": {
"remote": {
"host": "http://192.168.0.100:9200"
},
"index": "formshare_records",
"query": {
"match_all": {}
}
},
"dest": {
"index": "formshare_records"
}
}
'
But I get zero transfer:
{"took":34,"timed_out":false,"total":0,"updated":0,"created":0,"deleted":0,"batches":0,"version_conflicts":0,"noops":0,"retries":{"bulk":0,"search":0},"throttled_millis":0,"requests_per_second":-1.0,"throttled_until_millis":0,"failures":[]}
The index definition is the same on both sides:
{"settings": {
"index": {
"number_of_shards": 5,
"number_of_replicas": 1
}
},
"mappings": {
"properties": {
"project_id": {"type": "keyword"},
"form_id": {"type": "keyword"},
"schema": {"type": "keyword"},
"table": {"type": "keyword"}
}
}}
Both of them are under docker:

The container of 9201 can see the index of 9200:
sudo docker exec -it es01 /bin/bash

Any idea why reindex does not work? I tried without query but I get the same!
