Not sure if this is a bug or not but I thought I’d see if anyone else has tried this and experienced the same issue. I’m attempting to use the Tower API to add and remove hosts from a temp static inventory. Adding hosts works fine, but when I try to remove that same host, I get the following JSON output error: “"id" field must be an integer.”

`

- name: Get host ID

uri:  
url: [https://tower/api/v2/inventories/18/hosts/](https://tower/api/v2/inventories/18/hosts/)  
method: GET  
body\_format: json  
force\_basic\_auth: yes  
user: “{{ tower\_user }}”  
password: “{{ tower\_pass }}”  
validate\_certs: no  
status\_code: 200  
register: host\_list  
when: inventory\_action == ‘Remove Host’

- name: Remove server from, Tower inventory  
uri:  
url: [https://tower/api/v2/inventories/18/hosts/](https://tower/api/v2/inventories/18/hosts/)  
method: POST  
body:  
id: “{{ host\_id[0] | int }}”  
disassociate: true  
body\_format: json  
force\_basic\_auth: yes  
user: “{{ tower\_user }}”  
password: “{{ tower\_pass }}”  
validate\_certs: no  
status\_code: 204  
when: inventory\_action == ‘Remove Host’

`

Here’s the JSON output when it fails:

I’ve tried converting host\_id to int but that doesn’t resolve the issue. host\_name and inventory\_action are inherited from a Tower survey. Tower version 3.5, Ansible version 2.8.3

try this:

id: “{{ host\_id[0] | int \* 1 }}”
