Hi

I have the following in my playbook

- hosts: localhost  
tasks:

- name: echo output  
command: echo {{item}}  
register: echo\_output  
with\_items:

- hi

- hello

- debug: msg=“{{ echo\_output.results}}”

When I run this playbook, I am getting the following

RES1SMOHANAS-M1:ansible-portal\_platform smohanasundaram$ ansible-playbook -i inventory/sriDev.ini -c local portal\_platform\_liferay\_patches\_prestage.yml

Looks like stdout\_lines is not present in the “echo\_output.results”. Please let me know what could be wrong here.

Sri,  
It would help if the your output matched the playbook you are running.

Your problem task isn’t even in your test playbook!

> TASK: [debug msg=“{{ echo\_output.results|map(attribute=‘stdout\_lines’)|list}}”] \*\*\*  
> ok: [127.0.0.1] =\> {  
> “msg”: “[Undefined, Undefined]”  
> }

Anyway, this works for me on stable-2.0.0.1 on centos 7.  
I get the output below, which is probably what you are expecting:

ok: [t1] =\> {  
“msg”: [  
[  
“hi”  
],  
[  
“hello”  
]  
]  
}

Hi John

Do you mind sharing your playbook with me? So that I can take a look at the code.

Thanks  
Sri
