Mattermost Commands not working

[Phill93]

Environment

• Python version: 3.9.2
• Nautobot version: 2.0.5
• nautobot-chatops version: 3.0.1
• Mattermost version: 7.8.0

Expected Behavior

Working commands in Mattermost

Observed Behavior

Every time I send a command in Mattermost towards Nautobot I get the message "Command with a trigger of 'nautobot' returned response 500 Internal Server Error". The following messages can be found in the Nautobot log at DEBUG level:

Steps to Reproduce

1. Setup Plugin
2. Send Command over Mattermost

Would you mind double-checking the docs for Mattermost Setup. I believe there might be an issue with the permissions on the Bot Account. https://docs.nautobot.com/projects/chatops/en/latest/admin/install/mattermost_setup/#mattermost-setup

[Phill93]

This are the Settings for the Mattermost Bot Account

[snaselj]

Have you tried running invoke bootstrap-mattermost?

https://docs.nautobot.com/projects/chatops/en/latest/dev/dev_environment/#docker-development-environment

[Phill93]

I have no development environment in which I could use the Invoke command, the problem occurs in production

[smk4664]

@Phill93 This could also be due to an issue authenticating to Mattermost. It could be possible that the Celery Worker is not able to access the config. This could happen if you are using Environment Variables, but only have the Environment Variables on the Nautobot service, and not the Nautobot Worker. Alternatively, the token might be wrong. You can regenerate the token in Mattermost and copy it back into the config, if you do regenerate the code, make sure you copy it on the pop-up box that appears, once you close it only the id is shown in Mattermost, not the token itself.
