Mattermost Get All Reacts fails on 6.3

[chberti]

Describe the bug
I recently updated my mattermost instance from 5.X to 6.3. We use N8N as a mattermost bot to automate things.
One workflow we use gets all Reactions on a specific POST_ID. Since the update, getting all reactions on posts that do not contain any outputs an error on this node (continue on fail parameter does not work).
I do not know if this is more related to n8n or to mattermost though. I did not find any documentation on this 'bug'
on either of them.

Thank you in advance ! :)

To Reproduce
Steps to reproduce the behavior:

1. set up a running mattermost 6.3 instance
2. post a message in a channel
3. Use Get all reactions on the post ID
4. If no reaction present, will get a "Cannot read property '$error' of null"

Expected behavior
mattermost node should output an empty item in this case.

Environment (please complete the following information):

• OS: CentOS
• n8n Version 0.157.0

👋🏻 sorry for the delay on this one, I am going through some older issues at the moment and have just put in a PR to fix this which once reviewed should be available in the next release.
