Error in BlizzClient.TokenValidation

[jrsmile]

Hi, im sorry to not be able to give more information but i found a strange error:

when using:

	validation, _, err := euBlizzClient.TokenValidation(context.Background(), token)
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
	}

	err = e.Encode(validation)
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}

i get the following output:

invalid character '<' looking for beginning of value
{
  "exp": 0,
  "user_name": "",
  "authorities": null,
  "client_id": "",
  "scope": null
}

i can validate the received token myself and use it for other functions like Userinfo just fine, only the validation function seems to have a problem. i am using the following settings:

	euBlizzClient, err = blizzard.NewClient(blizzard.Config{
		ClientID:     clientID,
		ClientSecret: clientSecret,
		HTTPClient:   http.DefaultClient,
		Region:       blizzard.EU,
		Locale:       blizzard.DeDE,

while trying to find why this happens, i checked the wow dev documentation, they say:

We strongly recommend that developers use the more secure POST /oauth/check_token method.
