Fhenix Client SDK — Error Handling

Overview

All SDK operations return values directly and throw typed CofheError objects on failure (replacing the Result wrapper used by legacy cofhejs). Each CofheError has a code (CofheErrorCode enum) and a human-readable message. Use isCofheError(err) to narrow.

import { isCofheError, CofheErrorCode, Encryptable } from '@cofhe/sdk';

try {
  const [encrypted] = await client.encryptInputs([Encryptable.uint32(42n)]).execute();
} catch (err) {
  if (isCofheError(err)) {
    console.error(err.code);    // CofheErrorCode enum value
    console.error(err.message); // human-readable description
  }
}
