Error during convert to geopackage

[leendertvanwolfswinkel]

I did

schema.upgrade(backup=False, upgrade_spatialite_version=True)
schema.convert_to_geopackage()

On this spatialite: staging-test-0d1d2d-simple-infiltration.zip

And it gave me this error:

Traceback (most recent call last):
  File "C:\Users\leendert.vanwolfswin\Documents\migration_checker\migration_checker.py", line 35, in migrate_spatialite
    schema.validate_schema()

    raise MigrationMissingError(
threedi_schema.application.errors.MigrationMissingError: This tool requires at least schema version 228. Current version: 219.

During handling of the above exception, another exception occurred:
