I believe it's -1 which basically means nvarchar(max). ntext is a deprecated type, so moving to nvarchar would be the right thing to move for future proof
Unfortunately, LongString is created in the database as nvarchar(1), not nvarchar(max), so at this point, LongString metadata type cannot be used.
This bug is fixed with high priority and will be released in 13.25.0
Thank you for your patience and apologies for the problems it might have caused.
@Quan Mai: Could you clarify the date when the new release is expected, please?
It should be out this week, if nothing extraordinary happens. However that'd be a QA decision and I have no influence over that.
We worked on Payment Connector and created XML files for the custom payment meta class import. Two of the fields of the imported metaclass have a type of LongString. Please see the below meta field definition for details:
The above-described meta field is created in the database as a column with type nvarchar(1) using EPiServer.Commerce.Core.13.24.0, while on EPiServer.Commerce.Core.13.20.0, the same meta field is created as ntext type, using the same XML for the metaclass and meta fields import.
I did not found any release notes related to the metadata type changes. Since in EPiServer.Commerce.Core.13.20.0 the old types are available, the changes to the metadata types were applied in one of the versions between 13.20.0 and 13.24.0.

Are these changes final ones? If so, what type of metadata do you recommend to use instead of the old LongString type which mapped to ntext SQL data type?
