Intermittent Cloudflare Error 1101 caused by worker-bouncer runtime failures #80

Hi,
we are facing a production issue with crowdsec-cloudflare-worker-bouncer.

We understand and confirm that the Worker being recreated by the bouncer container is expected behavior.

However, we are experiencing intermittent Cloudflare Error 1101 (Worker threw exception) that appears and disappears every few minutes, even when:

Cloudflare itself is stable

Routes are unchanged

The Worker code is untouched

CrowdSec decisions are working correctly

Observed behavior:

Pages randomly fail with Error 1101, then recover automatically

WordPress admin actions (update/install) intermittently fail and receive the HTML Error 1101 response

The issue happens across multiple zones using the same bouncer

The failure is transient and loops over time

This strongly suggests a runtime failure inside the Cloudflare bouncer integration (KV/D1 access, bindings, rate limits, or exception handling), not a routing or Cloudflare-side configuration issue.

Questions:

Are there known conditions where the worker-bouncer throws uncaught exceptions during normal operation?

Is there a known issue with transient failures related to KV/D1, bindings, or decision sync?

Are there recommended safeguards or configs to prevent Error 1101 during normal reconcile cycles?

This is a blocking issue in production.

Thanks.
