Trouble serializing Schema.Class Instances with devalue (Svelte Kit)

import { query } from '$app/server';
import { Schema } from 'effect';

// Schema.Class instances can't be serialized with devalue
// Affects both remote functions and load functions in SvelteKit
// Schema.encode doesn't help

class SomeClass extends Schema.Class<SomeClass>('SomeClass')({
    test: Schema.String
}) {}

// This leads to `DevalueError: Cannot stringify arbitrary non-POJOs`
export const getDemoPlain = query(async () => SomeClass.make({ test: 'foo' }));

// I expected this to work, but the same error occurs
export const getDemoWithEncode = query(async () =>
    Schema.encode(SomeClass)(SomeClass.make({ test: 'foo' }))
);

import { stringify } from 'devalue';

// So i tried if plain devalue works, SvelteKit uses it internally
// So the problem is not with devalue, but with "devalueing" Schema.Class instances
export const getDemoWithDevalue = query(async () => stringify(SomeClass.make({ test: 'foo' })));
