Missing error messages

[manonromain]

Hi there,

Thanks for your work! One thing I find is missing is logging of error. For instance, when adding an entity without an id and putting it in the dataset, no errors occur even though the item was not actually added.

from ftmstore import Dataset, Store
from followthemoney import model

dataset = Dataset(store=Store(), name="test")
event = model.make_entity("Event")
# event.make_id("my_id") # let's say I forgot this line
dataset.put(event)

for elt in dataset.iterate():
    print(elt)

In that case, my dataset will be empty but I get no error or warning messages.

Best,
