matrix_appservice_discord_database_engine has been set to `postgres` (which is our new default now). path: "{{ matrix_appservice_discord_sqlite_database_path_local }}"
However, we've discovered an existing SQLite database in {{ matrix_appservice_discord_sqlite_database_path_local }}. register: matrix_appservice_discord_sqlite_database_path_local_stat_result
It appears that you've been using this bridge with the SQLite engine until now.
To continue using SQLite, opt into it explicitly: add `matrix_appservice_discord_database_engine: sqlite` to your vars.yml file and re-run this same command. - block:
Alternatively, to migrate your existing SQLite database to Postgres: - set_fact:
1. Stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`) matrix_postgres_db_migration_request:
2. Import the SQLite database into Postgres (`ansible-playbook -v -i inventory/hosts setup.yml --tags=import-generic-sqlite-db --extra-vars='sqlite_database_path={{ matrix_appservice_discord_sqlite_database_path_local }} postgres_connection_string_variable_name=matrix_appservice_discord_database_connString'`) src: "{{ matrix_appservice_discord_sqlite_database_path_local }}"
3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`) dst: "{{ matrix_appservice_discord_database_connString }}"
