获取Slack消息失败。

Error message

获取Slack消息失败。

What it means

A Slack API failure while fetching the bot's replies: get_slack_messages() calls conversations_history and wraps SlackApiError / KeyError in RuntimeError('获取Slack消息失败。'). SlackApiError means the Slack HTTP API returned an error payload (bad token, missing scope, invalid channel); KeyError means the response JSON lacked the expected 'messages' field.

Solutions

1. Verify SLACK_CLAUDE_USER_TOKEN is valid: curl -H 'Authorization: Bearer <token>' https://slack.com/api/auth.test
2. Add the required read scope (im:history / channels:history) to the token and reinstall the app
3. Check you are not rate-limited: the get_reply loop polls every 0.5s, back off if Slack returns 429
4. Catch SlackApiError and log e.response['error'] to see the exact Slack code (invalid_auth, channel_not_found, missing_scope, ratelimited)

Example fix

# before
except (SlackApiError, KeyError) as e:
    raise RuntimeError(f"获取Slack消息失败。")

# after
except SlackApiError as e:
    raise RuntimeError(f"获取Slack消息失败: {e.response['error']}") from e
except KeyError as e:
    raise RuntimeError(f"获取Slack消息失败: unexpected payload, missing {e}") from e

from slack.errors import SlackApiError
test = await client.conversations_history(channel=client.CHANNEL_ID, limit=1)
assert 'messages' in test, 'unexpected Slack payload shape'

try:
    msgs = await client.get_slack_messages()
except RuntimeError:
    logger.exception('conversations_history failed; token/scopes/rate-limit?')
    await asyncio.sleep(2)  # back off, loop continues
except Exception:
    raise

When it happens

Trigger: conversations_history(channel=CHANNEL_ID, oldest=LAST_TS, limit=1) failing inside the get_reply() polling loop of request_llms/bridge_stackclaude.py:67 — e.g. expired/revoked SLACK_CLAUDE_USER_TOKEN, token without channels:history scope, CHANNEL_ID pointing to an inaccessible channel, or Slack returning an error shape without resp['messages'].

Common situations: User token rotated or revoked after setup; bot removed from workspace; missing history scope on the legacy token; Slack rate limit (429) during the 0.5s polling loop; CHANNEL_ID stale after workspace migration.
