Migrating tracker store

[Deprecated] Rasa X Community Edition
1

I’ve followed the steps here to migrate the tracker store for Rasa X

https://rasa.com/docs/rasa-x/import-conversations/

my endpoints file looks like this:

tracker_store:
    type: redis
    url: <my_redis_url>
    port: 6379
    db: 0

I tried running the migration tool found here:

Migrates a Rasa tracker store (Redis, Mongo, SQL) to Rasa X. · GitHub

When I run the script, I get the following error:

Start migrating 50 trackers.

    dialogue = pickle.loads(_json)

Any idea what’s causing this?

Continuing the discussion from Migrating tracker store:

I am getting similar kind of issue as well while migrating redis.

It doesn’t look like the migration tool, or Rasa X support Redis Tracker Stores. I changed my endpoints.yml to point to a mongo instance, and everything works perfectly.
