Issues with migrating configuration to the Mattermost Database

Summary
Not able to migrate the configuration to the mattermost DB

Steps to reproduce
Successful curl response to MM server after Fresh install of Mattermost Version 6.6.0 with configuration to AWS Aurora DB.
Error after running commands:
sudo su mattermost
cd /opt/mattermost
bin/mattermost config migrate ./config/config.json ‘postgres://mmuser:@:5432)/mattermost?sslmode=disable&connect_timeout=10’

Expected behavior
config migrate runs

Observed behavior
Error: unknown command “config” for “mattermost”

Also get same response from “bin/mattermost config get SqlSettings.DataSource” command. After looking at --help I tried using “bin/mattermost --config get SqlSettings.DataSource” and get the error:
Error: unknown command “SqlSettings.DataSource” for “mattermost”

I’m using the instructions from:
https://docs.mattermost.com/configure/configuation-in-mattermost-database.html

the command listed on the page doesn’t work for me
bin/mattermost config get SqlSettings.DataSource

I get the error:
Error: unknown command "config" for "mattermost" Run 'mattermost --help' for usage.

Does it work for anyone else?
