Marsmallow 3.24.0 deprecates construction of Field

Commencez par workflows/util/zocalo/configuration.py, plus précisément par Pika.Schema.port, où fields.Field(required=True) émet l’avertissement de Marshmallow. Examinez le schéma environnant et la configuration des tests système, puis vérifiez que le chargement de la configuration de zocalo ne nécessite plus d’ignorer explicitement l’avertissement avec Marshmallow 3.24.0.

While running system tests for mx-bluesky, I encountered the following warning while loading the zocalo configuration, which we have had to add an explicit ignore for:

    warnings.warn(
marshmallow.warnings.ChangedInMarshmallow4Warning: `Field` should not be instantiated. Use `fields.Raw` or  another field subclass instead.

It seems that in 3.24.0 of marshamallow, they have deprecated this usage and are now generating warnings for it.
