Python middleware error when trying example from documentation

Hi Yegor,

I’m not able to recreate the problem, even when using the bundle you attached
A couple of things though.

You don’t need "driver": "python", specified in the API defn when you are using a bundle. That info comes from the manifest.

Perhaps most importantly, when you change or rebuild the bundle you have to either change its name and update the API defn or remove the directory containing it from under /opt/tyk-gateway/middleware/bundles and restart the gateway.

Here are the logs from loading and running your bundle.You can see the error returned from python about 100 being an int.

And here’s the section from the API

"custom_middleware": {
  "pre": [],
  "post": [],
  "post_key_auth": [],
  "auth_check": {
    "name": "",
    "path": "",
    "require_session": false,
    "raw_body_only": false
  },
  "response": [],
  "driver": "",
  "id_extractor": {
    "extract_from": "",
    "extract_with": "",
    "extractor_config": {}
  }
},
"custom_middleware_bundle": "tyk-plugins_bundle",

Cheers,
