How to Fix Phantombuster "Error during loading of chat widget”

When your messages vanish into thin air

You kick off a LinkedIn Message Sender Phantom, expecting smooth automation… but instead, the widget never loads and your messages never send. No warning, just a log entry reading “Error during loading of chat widget.” If you’ve felt helpless watching your message queue stall, read on.

What’s really happening?

This error stems from the LinkedIn chat interface failing to initialize in Phantombuster’s headless browser, typically due to:

  • Temporary glitches on LinkedIn’s side: site updates or momentary downtime can break widget loads.

  • Browser cache or cookie conflicts: stale data prevents the chat module from rendering.

  • Slow or unstable internet connection: the widget times out before fully loading.

  • Expired LinkedIn session: your session cookie has lapsed, so the chat iframe won’t authenticate.

Although Phantombuster is not at fault, the result is the same: your automated messages never fire.

1) Quick-fix: reload your automation in minutes

  1. Pause the Phantom

    • Stop the job in Phantombuster to prevent repeated failures.

  2. Refresh your session

    • In a browser, log into LinkedIn, then copy the latest session cookie (li_at) into Phantombuster’s settings.

  3. Clear cache & cookies

    • Open your browser’s settings, clear LinkedIn-related cache and cookies, then restart the browser.

  4. Wait and retry

    • Sometimes, a 5–10 minute pause is enough for LinkedIn’s glitch to resolve; then rerun the Phantom.

After these steps, the chat widget should load correctly and messages will go out.

2) Prevent future widget failures

  • Update your browser: keep Chrome/Firefox on the latest release to match Phantombuster’s engine.

  • Use a stable connection: avoid VPN drops or flaky Wi‑Fi during sends.

  • Schedule off-peak: run campaigns during LinkedIn’s lower-traffic hours to reduce server-side hiccups.

  • Automate retries: wrap your message step in a loop that retries up to 3 times on errors.

Incorporating these safeguards keeps your message steps reliable.

3) Why ReactIn never misses a beat
