Importing Affiliations using a Job does not work as stated in Docs

Package version (if known): Invenio v13

## Describe the bug
I tried following the docs to download the affiliations from ROR using a job: https://inveniordm.docs.cern.ch/operate/customize/vocabularies/affiliations/#import-using-a-job

however, it fails with the datetime format (YYYY-MM-DD) stated in the docs. It can be scheduled using the datetime format YYYY-MM-DDThh:mm:ss but then breaks shortly after due to a datetime formatting mismatch (see stack trace). Images are attached for further details. Importing worked via command line btw.
