Odoo Server Error "keys must be str, int, float, bool or None, not frozendict"

[ramon-it]

With this code im trying to get data of model account.payment:

var repository = new OdooRepository<AccountPaymentOdooModel>(client.Config); var res = await repository.Query().ToListAsync();

I got AccountPaymentOdooModel object from:

OdooModelMapper.GetDotNetModel

I have the error "keys must be str, int, float, bool or None, not frozendict". Any idea how to solve it?

Thanks!
