The type order of optional arguments affects the results #189
Open
Description
I used version: 1.6.1. The following program is correct:
s = "mode: default"
schema_map = {
"mode": sy.Str(),
sy.Optional("duration", default=None, drop_if_none=False): sy.EmptyNone()
| sy.Float(),
}
config_yaml = sy.load(
yaml_string=s,
schema=sy.Map(schema_map),
)But when I change the type order of optional duration like following:
s = "mode: default"
schema_map = {
"mode": sy.Str(),
sy.Optional("duration", default=None, drop_if_none=False): sy.Float()
| sy.EmptyNone(),
}
config_yaml = sy.load(
yaml_string=s,
schema=sy.Map(schema_map),
)then there would be an error, here is the error log:

But if changing sy.Float() to sy.Int(), this error would not arise.
