Hi,

In my roles I use the following Handler definition:

`

- name: restart prometheus  
include: “roles/common/tasks/restart-service.yml service\_name=prometheus”  
`

This works fine in 2.7.10.

After updating to 2.8.0 I got the following error:

> ERROR! The requested handler ‘restart prometheus’ was not found in either the main handlers list nor in the listening handlers list

I have tried several variants:

`

- name: restart prometheus  
import\_tasks: roles/common/tasks/restart-service.yml  
vars:  
service\_name: prometheus  
`

Same Problem.

If I use a simple debug statement it works:

`

- name: restart prometheus  
debug:  
msg: System {{ inventory\_hostname }} has uuid {{ ansible\_product\_uuid }}

`

I realize that you should avoid dependencies between roles but repeating a block of code over and over doesn’t seem to be a good solution either.

Any idea?

Regards Philipp

You have a few issues, one you have already attempted to address.

1. Don’t use `include` as it has behavior that cannot be easily reasoned and understood in many cases
2. A change was made in Ansible 2.8 that is documented in the porting guide, preventing you from using a static include or `import_tasks` as a handler itself. This is described in more detail at [https://docs.ansible.com/ansible/latest/porting\_guides/porting\_guide\_2.8.html#imports-as-handlers](https://docs.ansible.com/ansible/latest/porting_guides/porting_guide_2.8.html#imports-as-handlers)

Effectively, what you need is to switch to `include_tasks`:

- name: restart prometheus  
include\_tasks: roles/common/tasks/restart-service.yml  
vars:  
service\_name: prometheus

Hi Matt  
thanks so much with include\_tasks it works.

Best regards
