Non-existing or expired scroll identifier when exporting collection / index from Kourou

[tdislay]

Expected Behavior

kourou index:export tenant-[group]-[name]
Should be able to dump collections with more than 2000 documents.
Same thing with kourou collection:export tenant-[group]-[name] [my-collection].

Current Behavior

I get the following error while dumping a collection with 13398 documents:

(I've tried with node 14 & updating kourou & using batch-size, but it has a limit)

Steps to Reproduce

1. Import a collection with more than 2000 documents (see documents.jsonl.txt and mappings.json.txt) into your kuzzle: kourou collection:import [../../]
2. Export the collection kourou collection:export tenant-[group]-[name] [collection]

Context (Environment)

Trying to export a collection in order to backup data
NodeJS 14 / 16
Kuzzle: 2.19.5
Kourou : kourou/0.24.2 linux-x64 node-v14.20.1

Seems related to #159, can you try extending the scroll duration with scrollTTL parameter?

[tdislay]

My connection is too slow, that's the problem

[Aschen]

Then you should increase the scroll TTL so it won't timeout
