Blocking Error with charset_normalizer in a Dynatrace Custom Extension on a Linux ActiveGate

gusmazeikis — Thu, 04 Sep 2025 10:06:38 GMT

Current Setup:

Dynatrace Managed version 1.286.86
Environment ActiveGate 1.285.30.20240227-095656 (OS Linux, x86, 64bit)
Extensions 1.285.161.20240417-193840
Python extension 2.0, developed in VsCode 1.90.0 (user setup), OS: Windows_NT x64 10.0.19045
- Python version: 3.10
- Pip version: 24.0
- Current library used: charset_normalizer-3.3.2-cp310-cp310-win_amd64.whl (Windows-specific)

Observed Error:

/var/lib/dynatrace/remotepluginmodule/log/extensions/ruxitagent_extensionsmodule_3086451.0.log

ERROR: Could not find a version that satisfies the requirement charset-normalizer<4,>=2 (from requests) (from versions: none)

Possible Explanation: The error is likely due to using the Windows-specific Wheel file charset_normalizer-3.3.2-cp310-cp310-win_amd64.whl on a Linux system. This incompatibility causes the extension to fail.

Proposed Solution: Use a platform-agnostic version of the library. It is suggested to use charset_normalizer-3.3.2-py3-none-any.whl, which should be compatible with both Windows and Linux environments.

By default pip will not use that cross-os compatible version, but the SDK already has a solution for that, we download both versions (windows and linux) when building

Please see here and here

Hi guys,

Any one knows how to use dt-sdk build --extra-platform manylinux2014_x86_64 from vscode?

Thanks in advance

Yos

There is an item in the vscode settings called "Dynatrace Extensions: Python Extra Platforms"

You add "manylinux2014_x86_64" to that list
