ValueError: Invalid isoformat string

Hi,

I have an issue with syncing QField cloud 4.17.0 updated at 05/09/2025 14:07 BST on QGIS version 3.40.5-Bratislava. My project will not sync and is erroring with “ValueError: Invalid isoformat string: '06.09.2025 09:02:10 UTC” This appears to be associated with the project creation date. Could anyone help resolve this, please?

Thanks,

Dean

I’m having this error as well now. “ ValueError: Invalid isoformat string: ‘06.09.2025 20:19:52 UTC’“

I am NOT a Python programmer, but here’s what I see.

a code snippet in cloud_transfer_dialog.py:

cloud_updated_at = 0.0
if project_file.updated_at:
cloud_updated_at = datetime.fromisoformat(project_file.updated_at) ← Line 798
is_local_checked = local_updated_at > cloud_updated_at

I don’t see any place where ‘project_file_updated_at’ is initialized with a date and time.

OK, they caught it and updated the Qfieldsync plugin. It’s working again.

Thank you for fixing this :slight_smile:
