How should I bridge two Twitter accounts?

I have two Twitter accounts and I want to manage their messages together.

However, mautrix-twitter’s Twitter Bridge Bot can only login one account ones. So I started thinking whether I could start 2 mautrix-twitter bridges to catch all messages.

I think I’m 90% done: I could login using the second twitter bot, however, I could not receive messages because there’re still some conflicts.

Here is how I deploy the second bridge:

Creating the second database

docker exec postgres createdb -U synapse_user -O synapse_user matrix_twitter_s1

Making a new directory and config for new bridge

mkdir mautrix-twitter-s1
docker run --rm -v `pwd`/mautrix-twitter-s1:/data:z dock.mau.dev/mautrix/twitter:latest

In mautrix-twitter-s1/config.yaml (only listing changes)

homeserver:
  address: http://synapse:8008
  domain: example.com

appservice:
address: http://mautrix-twitter-s1:29328

port: 29328

database: postgres://synapse_user:hello@postgres/matrix_twitter_s1?sslmode=disable
  id: twitter-s1
  bot_username: twitterbot-s1
  bot_displayname: Twitter bridge bot s1

bridge:
  username_template: twitter_s1_{userid}
  displayname_template: "{displayname} (Twitter)"

  double_puppet_server_map:
    matrix.server: https://example.com
  login_shared_secret_map:
    example.com: <redacted>

  command_prefix: "!tw1"

  permissions:
    example.com: user
    "@admin:example.com": admin

Register the new bridge

After editing the config, I run

docker run --rm -v `pwd`/mautrix-twitter-s1:/data:z dock.mau.dev/mautrix/twitter:latest

again to get registration.yaml:

id: twitter-s1
as_token: <redacted>
hs_token: <redacted>
namespaces:
    users:
    - exclusive: true
      regex: '@twitter_s1_.*:example\.com'
    - exclusive: true
      regex: '@twitterbot\-s1:example\.com'
    aliases: []
url: http://mautrix-twitter-s1:29328
sender_localpart: <redacted>
rate_limited: false
de.sorunome.msc2409.push_ephemeral: true
push_ephemeral: true

Then I register the bridge to synapse:

cp mautrix-twitter-s1/registration.yaml synapse/tw-s1-registration.yaml
sudo chown 991:991 synapse/tw-s1-registration.yaml

And in synapse/homeserver.yaml:

app_service_config_files:
  - /data/tw-s1-registration.yaml

Start the container

Then I edit the docker-compose.yml, adding lines below. I have already set another bridge by then, so here I show thier config together.

  mautrix-twitter:
    hostname: mautrix-twitter
    container_name: mautrix-twitter
    image: dock.mau.dev/mautrix/twitter:latest
    restart: unless-stopped
    depends_on:
      synapse:
        condition: service_healthy
    volumes:
      - ./mautrix-twitter:/data
    networks:
      - matrix-net
  mautrix-twitter-s1:
    hostname: mautrix-twitter-s1
    container_name: mautrix-twitter-s1
    image: dock.mau.dev/mautrix/twitter:latest
    restart: unless-stopped
    depends_on:
      synapse:
        condition: service_healthy
    volumes:
      - ./mautrix-twitter-s1:/data
    networks:
      - matrix-net

Encounter problems

Then I use docker-compose up -d to start my service, start a chat with @twitterbot-s1:example.com.

I could successfully login:

...but when the brige try to sync msgs, it encounter such problems:

I tried to change displayname_template from "{displayname} (Twitter)" to "{displayname} (Twitter-s1)" in order to solve possible conflicts, but problem remains.

Could anyone give me some ideas on how should I solve this? Or, should I attach the configration of my first twitter brige (which works fine)?
