Hi,Knimer When re-install knime 5.4.3, the local GPT4ALL node was missing. After uninstall KNIME AI Extension, then re-install AI Extension again. It still can’t solve this issue. How to fix it? [image] [image] [image] Cannot complete the request. See the error log for details. "KNIME AI Extension" will be ignored because it is already installed.```

Hi @eddy0620 , If you are on macOS 15.4 you are maybe affected by Known macOS 15.4 Issue with KNIME’s Bundled Python Environments . In any case, there should be a log entry starting with “Failed to parse Python node extension” in your KNIME Log (Menu → Show KNIME Log in File Explorer → knime.log) with details about why the extension could not be loaded. Could you post the details here?
