I found that this encapsulates the error information. This is
Any special reason?

func (f *Fosite) DefaultClientAuthenticationStrategy(ctx context.Context, r *http.Request, form url.Values) (Client, error) {
        ...
	client, err := f.Store.GetClient(ctx, clientID)
	if err != nil {
		return nil, errorsx.WithStack(ErrInvalidClient.WithWrap(err).WithDebug(err.Error()))
	}
        ...
}

fosite/errors.go

	ErrInvalidClient = &RFC6749Error{
		ErrorField:       errInvalidClientName,
		DescriptionField: "Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method).",
		CodeField:        http.StatusUnauthorized,
	}
