Bug description

Hi @vboufleur

Please update your templates to the latest definition format: http://portainer.readthedocs.io/en/stable/templates.html

This error is due to the fact that you need to use an integer for the type property. Note that external templates are not really supported at the moment in the 1.19.1, you might be interested in https://github.com/portainer/portainer/pull/2119 (which can be tested via portainer/portainer:pr2119).
