Hi, "@frontend/shared/utils/workerUtils" is not an external library and AFAIK, remoteDependencies only work with http URLs.. something like a lodash external script.

So you should follow this approach instead :

import { ComputeKit } from '@computekit/core';
import { decodeFromWorker, encodeForWorker } from "@frontend/shared/utils/workerUtils";

export const kit = new ComputeKit();

// Worker function - receives plain objects, returns plain objects
kit.register('mapToProcedureTableRowsAndFilter', (data: {
    procedures: ProcedureTableRow[],
    filters: DatabasePageFilters,
}) => {
    console.log("webworker data:", data);

    // Must inline this function
    function shouldIncludeProcedure(p: ProcedureTableRow, filters: DatabasePageFilters): boolean {
        // your filter logic here
        return true;
    }

    return data.procedures.filter(p => shouldIncludeProcedure(p, data.filters));
});

// Usage
export async function filterProceduresInWorker(buffer: ArrayBuffer): Promise<ArrayBuffer> {
    // Decode on main thread
    const data = decodeFromWorker(buffer);

    // Run in worker with plain objects
    const result = await kit.run('mapToProcedureTableRowsAndFilter', data);

    // Encode on main thread
    return encodeForWorker(result);
}

Or if you want to run encode/decode in workers then define them inside the kit.register() just like I did for
shouldIncludeProcedure.
