[BUG] invalid character '-' in numeric literal.

[Priyal1995]

Describe the bug

I've recently switched the to go-micro v4 & started getting this error while using the function config.Load().

It was supposed to load the config instead I am getting this error -> invalid character '-' in numeric literal

How to reproduce the bug

func loadConfigFile() error {
	enc := yaml.NewEncoder()

	// Configmap Path
	configMapPath, set := common.GetEnvVar("CONFIGMAP_PATH", "./testdata", true)
	if !set {
		return common.GetErrEnvVar("CONFIGMAP_PATH")
	}
	// Configmap yaml file name
	configMapFile, set := common.GetEnvVar("CONFIGMAP_FILE", "data.yml", true)
	if !set {
		return common.GetErrEnvVar("CONFIGMAP_FILE")
	}
	// Secret Path
	secretPath, set := common.GetEnvVar("SECRET_PATH", "./testdata", true)
	if !set {
		return common.GetErrEnvVar("SECRET_PATH")
	}
	// Secret yaml file name
	secretFile, set := common.GetEnvVar("SECRET_FILE", "secrets.yml", true)
	if !set {
		return common.GetErrEnvVar("SECRET_FILE")
	}

	// Load config sources
	if err := config.Load(
		file.NewSource(
			file.WithPath(configMapPath+"/"+configMapFile),
			source.WithEncoder(enc)),
		file.NewSource(
			file.WithPath(secretPath+"/"+secretFile),
			source.WithEncoder(enc),
		)); err != nil {
		        fmt.Println(err)
		)
		return errLoadConfigFile
	}

	// Watch a value for changes
	watcher, err := config.Watch()
	if err != nil {
	       fmt.Println("Error 2!")
		)
		return errWatchFileError
	}

	go processConfig(watcher)
	return nil
}
