Failed due to deprecation of ModelSchema in marshmallow-sqlalchemy-0.26.0: https://github.com/marshmallow-code/marshmallow-sqlalchemy/blob/03c2cfcb09992020a855a31218e91f32ebc9eb14/CHANGELOG.rst#0260-2021-05-26

Set to highest version of 0.25.1 to stop 0.26.1 being pulled when building that caused previous fail:
