Unable to get local issuer certificate

hi again 🙂 I'm getting this error

workerd/jsg/util.c++:276: error: e = kj/compat/tls.c++:215: failed: TLS peer's certificate is not trusted; reason = unable to get local issuer certificate

it only appears when I use service bindings like this:

serviceBindings[bindingName] = req => {
  const smf = new Miniflare(options)
  return smf.dispatchFetch(req)
}

serviceBindings[bindingName] = req => {
  const smf = new Miniflare(options)
  return smf.dispatchFetch(req)
}

Hey! 👋 What version of Miniflare, Node and operating system are you using? What is the script in options doing? Are you making any outbound fetch calls to HTTPS services?

I think I do have an existing HTTPS outbound call to honeycomb for tracing spans, will see if I can disable that during dev. thanks!

Any chance you’ve got Cloudflare WARP enabled too?

matt // unwebOP•2y ago

No, I've not heard of WARP (but looks useful, thanks!) It was the instrumentation library trying to send spans to the HTTPS honeycomb collector, so I've disabled it and the errors no longer appear 🙂

Hmm, good that fixes things, but that’s not ideal. What operating system including version are you on again?
