from slack_bolt import App
from slack_bolt.adapter.socket_mode import SocketModeHandler

bot_token = os.environ.get("SLACK_BOT_TOKEN")

Requirements

N/A?

Workaround

Using the websocket_client handler, and specifying the proxy settings manually.

from slack_bolt import App
from slack_bolt.adapter.socket_mode.websocket_client import SocketModeHandler

bot_token = os.environ.get("SLACK_BOT_TOKEN")
app_token = os.environ.get("SLACK_APP_TOKEN")

app = App(token=bot_token)
socketAdapator = SocketModeHandler(
    app,
    app_token,
    http_proxy_host="proxy_host",
    http_proxy_port="3128",
)
