openclaw - 💡(How to fix) Fix [BUG] LINE channel: dmPolicy:"open" silently drops all incoming messages [1 comments, 2 participants]

Describe the bug

When dmPolicy: "open" is configured for the LINE channel, all incoming messages are silently dropped. The webhook returns 200 OK, but messages never reach the agent session. No errors are logged.

Root Cause

mergeDmAllowFromSources() in allow-from-L4GtxkFC.js does not add a wildcard "*" entry when dmPolicy is "open". This results in an empty allowlist, causing isSenderIdAllowed() to return false silently. The message is dropped by shouldProcessLineEvent().

Code

File: allow-from-L4GtxkFC.js → mergeDmAllowFromSources

Before (broken):

function mergeDmAllowFromSources(params) {
    const storeEntries = params.dmPolicy === "allowlist" || params.dmPolicy === "open" ? [] : params.storeAllowFrom ?? [];
    return normalizeStringEntries([...params.allowFrom ?? [], ...storeEntries]);
}

After (fixed):

function mergeDmAllowFromSources(params) {
    const storeEntries = params.dmPolicy === "allowlist" || params.dmPolicy === "open" ? [] : params.storeAllowFrom ?? [];
    const entries = [...params.allowFrom ?? [], ...storeEntries];
    if (params.dmPolicy === "open") entries.push("*");
    return normalizeStringEntries(entries);
}

Impact

• LINE users with dmPolicy: "open" cannot receive any messages
• Bug is invisible: webhook returns 200 OK, no error logs

To Reproduce

1. Configure LINE channel with dmPolicy: "open"
2. Send a message from LINE to the bot
3. Webhook receives event (200 OK)
4. Message never reaches agent; no error logged

Expected behavior

dmPolicy: "open" should allow all incoming messages from LINE.
