"argument 'myapp_int' is of type <class 'ansible.parsing.yaml.objects.AnsibleUnicode'> and we were unable to convert to int: <class 'ansible.parsing.yaml.objects.AnsibleUnicode'> cannot be converted to an int"
],
unable to convert to int とあるので、変換しようとしてエラー、ということのようです。 なお、myapp_int: "123" という指定はエラーになりませんでした。
