You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: config.go
    path of file: ./repos/chainlink/core/services/ocr2/plugins/llo/config
    
    the code of the file until where you have to start completion: // config is a separate package so that we can validate
// the config in other packages, for example in job at job create time.

package config

import (
	"encoding/json"
	"errors"
	"fmt"
	"net/url"

    
func validateKeyBundleIDs(keyBundleIDs map[string]string) error {
	for k, v := range keyBundleIDs {
		if k == "" {
			return errors.New("llo: KeyBundleIDs: key must not be empty")
		}
		if v == "" {
			return errors.New("llo: KeyBundleIDs: value must not be empty")
		}
		if _, err := llotypes.ReportFormatFromString(k); err != nil {
			return fmt.Errorf("llo: KeyBundleIDs: key must be a recognized report format, got: %s (err: %w)", k, err)
		}
		if !chaintype.IsSupportedChainType(chaintype.ChainType(k)) {
			return fmt.Errorf("llo: KeyBundleIDs: key must be a supported chain type, got: %s", k)
		}

	}
	return nil
