Error: failed to load MAS config: missing field matrix #5212
Description
Describe the bug
I can't launch mas-cli syn2mas check as root, I get an error about database.
And if I launch it as postgres user, then it tells me about this error
Error: failed to load MAS config: missing field matrix``
even though in opt/mas/config.yaml file, I have something like :
passwords:
enabled: false
schemes:
- version: 1
algorithm: argon2id
minimum_complexity: 3
matrix:
kind: synapse
homeserver: defis.info
secret: averylongsecret
endpoint: https://matrix.mytld.com/
upstream_oauth2:
providers:
Here are the command I run and the output of them :
root@matrix:~# /opt/mas/mas-cli syn2mas check --config /opt/mas/mas_config.yaml --synapse-config /etc/matrix-synapse/homeserver.yaml
