Hi all,
recently I tried to deploy a custom extension on activegate. Looking at the logs I noticed the following errors. 

2024-08-05 14:47:04.469 UTC [003946f3] warning [native] Failed to prepare extension environment:

Could you help me to understand what happened?

Other details:

• Looking in links: /var/lib/dynatrace/remotepluginmodule/agent/runtime/extensions/cache/custom_keycloak-ext/0.0.3/lib --> lib folder doesn't exist.
  
  The error seems to be the missing folder:
  WARNING: Location '/var/lib/dynatrace/remotepluginmodule/agent/runtime/extensions/cache/custom_keycloak-ext/0.0.3/lib' is ignored: it is either a non-existing path or lacks a specific scheme.
  
  How I can force the creation of lib (and eventually other resources) folder?

Is keycloak_ext the name of your extension or a python package?

If the former, then something weird happened with your build. Share the contents of the extension.zip file you are using, as well as how you built it.

If the latter, this usually happens when you build the extension in one platform but try to run it in another -- pip might miss downloading wheels for the platform you are trying to run on. Check what OS you are trying to run the extension on and whether the extension.zip file has the wheels required to install all packages for that OS.
