Hi, I also have an account with just numbers and upgrading to 28.04 fixed Folders displaying within Nextcloud with your patch, thank you.

I am however also experiencing a similar issue when attempting to add additional paths to Timeline view within the Memories app. The console window provides a very similar error. Is this the same issue by chance?

Additionally, I do not have this same problem within my other account with a username that is not just numbers.

@ChildLearningClub best you report this on the Memories app. Here: https://github.com/pulsejet/memories/issues

Might be that they use an old library version.
