Please be so kind and update https://github.com/abraunegg/onedrive/blob/master/docs/Docker.md with information provided in issue #1770 (comment)
I've tried to setup https://github.com/abraunegg/onedrive/blob/master/docs/advanced-usage.md#upload-data-from-the-local-onedrive-folder-to-a-specific-location-on-onedrive but still have the same error: Skipping item - invalid symbolic link: ./xxxx
Now it's clear to me that was not accessible in the container.
Thank you.
