[Solved] Importing from Slack missing emoji reactions in replies

Troubleshooting
1

Summary
Imported reply threads are missing their emoji reactions.

Steps to reproduce
Running Mattermost 9.11.6 currently

Followed this guide and everything worked as specified, except for emoji reactions on reply posts:

This is the format of a post in the jsonl file that is being imported here. It includes data for reactions to a reply but they do not show up in Mattermost.

{“type”:“post”,“post”:{“team”:“my-team”,“channel”:“channel-name”,“user”:“user-name”,“type”:“”,“message”:“message-text”,“props”:null,“create_at”:1742951653352,“edit_at”:null,“reactions”:,“replies”:[{“user”:“user-name”,“type”:null,“message”:“reply-text”,“create_at”:1742952630836,“edit_at”:null,“reactions”:[{“user”:“user-name”,“create_at”:1742952630837,“emoji_name”:“grinning”},{“user”:“user-name”,“create_at”:1742952630837,“emoji_name”:“+1”}],“attachments”:}],“attachments”:}}

Normal posts have their emoji reactions as expected.

Update: I have upgraded my Mattermost instance to 10.5.2 and re-imported my Slack data file and now the reaction emojis appear on replies as expected.
