I wrote a custom plugin to control the permission of my application deployed in k8s.
The upstream is a code-server web application.
It can be accessed normally under nginx-ingress.
When I switched from ingress to apisix, most requests can be proxied normally, except for one ttf request like:

http://a1.webide.demo.test/static/out/vs/base/browser/ui/codicons/codicon/codicon.ttf?5d4d76ab2ce5108968ad644d591a16a6
This request returned 503.

Then I looked at the log of apisix, I saw the following error messages:

It seems that some part of the plugin that I haven't changed has blocked the TTF request. Maybe bugs?
How to solve this problem?

Attach my apisixroute:

apiVersion: apisix.apache.org/v2beta2
kind: ApisixRoute
metadata:
  name: webide-test
  namespace: dev-3woklfan
spec:
  http:
  - name: rule1
    match:
      hosts:
      - a1.webide.demo.test
      paths:
      - /*
    backends:
    - serviceName: webide-ad5c19-ad5c19-svc
      servicePort: 30000
    websocket: true
    plugins:
    - name: ext-plugin-pre-req
      enable: true
      config:
        conf:
        - name: "authorization"
          value: "{\"test\": \"test\"}"

@dantegarden We want to use the python runner in K8s, but are trying to do it with standard container using helm, and mounting the plugin as extra Volumes/mounts .. the debian 3.3.0 image does not have python installed. AM interested in how you achieved getting the runner working .. Thanks in advance
