I’m running ansible 2.5.5-1. It seems that the issue I have where the nxos\_module spits out an error seem to be related to the version or image on the device I’m trying to connect to. I think the error is saying that the object containing stdout doesn’t have a get() method. “unicode”, that there is like a sub-class of string, right? I’m reading thru issues on git-hub, but they talk way over my head. ELI5 (Explain it Like I’m 5); IS this fixed in 2.6? Is this a “too bad, so sad” sort of issue where I just need to get newer switches or older ansible?

Dennis, I’m not an expert on networking but, we can try to gather some information and track it down. How does your playbook/role look like ? did you follow the instructions in here [https://docs.ansible.com/ansible/2.5/network/user\_guide/platform\_nxos.html#nxos-platform-options](https://docs.ansible.com/ansible/2.5/network/user_guide/platform_nxos.html#nxos-platform-options)? ---

Hi, You are getting this error on 5.2(1)N1(1) Nexus as JSON structured output is not supported on the device. Non structured output support for this module is added in 2.6. Please upgrade to Ansible 2.6.2. Thanks, ---

Jonathan, Your response sounds like you’ve never heard this sort of thing before, which kinda strike me as odd in light of the issues in github. But yes, I’ve followed the recommendations you reference. Here is an example of the one of the many tasks that produce this type of error: - name: “Gathering HW Facts” nxos\_facts: gather\_subset: default provider: “{{ provider }}” register: “hw\_facts” when: “os ==‘nxos’” ---

Ok, so I bit the bullet and upgraded to ansible 2.6.2. The nxos\_facts command no longer blows up on the older images. It doesn’t return any actual facts either, but not blowing up is good - maybe. I do like the idea of failing early and failing loudly. “hw\_facts”: { “ansible\_facts”: { “ansible\_net\_gather\_subset”: [ “default” ], “ansible\_net\_hostname”: null, “ansible\_net\_image”: null, “ansible\_net\_model”: null, “ansible\_net\_serialnum”: null, “ansible\_net\_version”: null }, “changed”: false, “failed”: false }
