@yurishkuro hey can i take this up

feel free

@yurishkuro
I Implemented this in this way is this the correct pattern to Implement or should the pass ErrorLog in ServerConfig Struct
sorry but i am kind a newbie to this

	errHandler func(w http.ResponseWriter, r *http.Request, errorMsg string, statusCode int)
	decoders   map[string]func(body io.ReadCloser) (io.ReadCloser, error)
	errorLog   *log.Logger
}
func WithErrorLogger(logger *log.Logger) ToServerOption {
	return toServerOptionFunc(func(opts *toServerOptions) {
		opts.errorLog = logger
	})
}

there is no need for new options - the ToServer function already receives a logger via telemetry settings. It can just assign ErrorLogger.

So you mean to say the Error Logger Should always be Zap.logger and the client should not get any option to give his own logger?

yes. It's a bug fix, not a capability.
