should `Dict`s be a valid dagster type in a Field config? I'm trying to create a

Field

with a Dict type, but getting

DagsterInvalidDefinitionError

. tried both the dagster Dict (

from dagster import Dict

) and the typing Dict. the error message seems to imply Dicts and NamedDicts are valid, though

yes that should work fine, can you include a bit more of what the definition looks like?

sure, here's the decorator:

ah, I see the issue! so

Dict

expects to have explicit schema of the fields it contains, e.g.

Field(Dict({'some_key': Field(str)}))

I think what you want here is probably

PermissiveDict

which permits arbitrary key-value pairs

boom, that worked. thanks @nate!

metal awesome. yeah our docs on this are unfortunately rather buried in the API docs here https://dagster.readthedocs.io/en/0.6.3/sections/api/apidocs/types.html#dagster.Dict
