    }),

loggerLink({
      enabled: (op) =>
        process.env.NODE_ENV === 'development' ||
        (op.direction === 'down' && op.result instanceof Error),
    }),

          trpcLogger.error(op.result);
          trpcLogger.error(
            op.result.cause?.cause,
            'Aggregated trpc error cause',
          );
        }
      },
      enabled: (op) =>
        process.env.NODE_ENV === 'development' ||
        (op.direction === 'down' && op.result instanceof Error),
    }),

loggerLink({
      logger: (op) => {
        if (op.direction === 'down' && op.result instanceof Error) {
          trpcLogger.error(op.result);
          trpcLogger.error(
            op.result.cause?.cause,
            'Aggregated trpc error cause',
          );
        }
      },
      enabled: (op) =>
        process.env.NODE_ENV === 'development' ||
        (op.direction === 'down' && op.result instanceof Error),
    }),
