Getting DataCloneError while using instance of a class as return value of RPC method
also works when i pass logger as a function, a bit weird that passing a class instance to the RPC stub does not work because the structured clone algorithm can copy a class instance solution: 
  const paymentService = await c.env.PAYMENTS.newPaymentService(() => services.logger);
  const paymentService = await c.env.PAYMENTS.newPaymentService(() => services.logger);

works well when i don't pass services.logger, does this mean i can't pass any variable to the class instance ? @Hard@Work

this is how Payments class looks like too 
class Payments extends RpcTarget {
  logger: Logger;

 constructor(logger: Logger) {
   super();
   this.logger = logger;
  }
}
class Payments extends RpcTarget {
  logger: Logger;

 constructor(logger: Logger) {
   super();
   this.logger = logger;
  }
}

This is what services look like: 
import { Env } from "../env";
import type { Logger } from "@paycashless/worker-logger";
import type { Metrics } from "../metrics";

export type ServiceContext = {
  logger: Logger;
  metrics: Metrics;
};

export type HonoEnv = {
  Bindings: Env;
  Variables: {
    requestId: string;
    services: ServiceContext;
    /**
     * IP address or region information
     */
    location: string;
    userAgent?: string;
  };
};
import { Env } from "../env";
import type { Logger } from "@paycashless/worker-logger";
import type { Metrics } from "../metrics";

export type ServiceContext = {
  logger: Logger;
  metrics: Metrics;
};

export type HonoEnv = {
  Bindings: Env;
  Variables: {
    requestId: string;
    services: ServiceContext;
    /**
     * IP address or region information
     */
    location: string;
    userAgent?: string;
  };
};
Logger is a custom logger, wrapped around console.log
