Slack threads get imported as individual messages

[lpilz]

Description:

When importing a Slack export, the messages which were in Threads on the Slack server are being imported as individual messages, not as Threads to Rocket.Chat.

Steps to reproduce:

1. Export Data from Slack
2. Import Data to Rocket.Chat

Expected behavior:

When importing threaded messages from Slack one would expect them to be threaded in Rocket.Chat as well.

Actual behavior:

These imported messages, which were threaded in Slack are not threaded in Rocket.Chat but imported as individual messages in the Channels.

• Version of Rocket.Chat Server: 3.0.2
• Operating System: Ubuntu 18.
• Deployment Method: snap
• Number of Running Instances: 1

It probably is. Is there any ongoing effort to implement this functionality? And/or (how) could I contribute there?
