How to get only stdout_lines with Ansible using mail module

I'm using ansible to scan hosts with clam antivirus and I'm receiving reports via email. Reports contain everything and I want only to receive stdout lines. Is there any way to accomplish this? I wrote email template according to https://gist.github.com/halberom/0aea275632d2b47af0536e5def01d4d2 although only thing that is not the same is that I've piped to nice json: The {{ host }} says {{ hostvars[host]['result']['stdout'] | to_nice_json }} The error I get is: > Unable to convert data using to_nice_json, falling back to to_json: 'dict object' has no attribute 'stdout'. the task includes an option with an undefined variable the error was ansible no_log:false If I remove

['stdout']

then email report looks like this: ClamAV scan was performed on host_server { "changed": true, "msg": "All items completed", "results": [ { "ansible_loop_var": "item", "changed": true, "cmd": [ "clamscan", "-r", "-i", "/usr/bin" ], "delta": "0:00:37.293719", "end": "2021-09-09 18:47:55.626094", "failed": false, "invocation": { "module_args": { "_raw_params": "clamscan -r -i /usr/bin", "_uses_shell": false, "argv": null, "chdir": null, "creates": null, "executable": null, "removes": null, "stdin": null, "stdin_add_newline": true, "strip_empty_ends": true, "warn": true } }, "item": "/usr/bin", "rc": 0, "start": "2021-09-09 18:47:18.332375", "stderr": "", "stderr_lines": [], "stdout": "\n----------- SCAN SUMMARY -----------\nKnown viruses: 8563204\nEngine version: 0.103.2\nScanned directories: 1\nScanned files: 701\nInfected files: 0\nData scanned: 110.08 MB\nData read: 109.50 MB (ratio 1.01:1)\nTime: 37.113 sec (0 m 37 s)\nStart Date: 2021:09:09 18:47:18\nEnd Date: 2021:09:09 18:47:55", "stdout_lines": [ "", "----------- SCAN SUMMARY -----------", "Known viruses: 8563204", "Engine version: 0.103.2", "Scanned directories: 1", "Scanned files: 701", "Infected files: 0", "Data scanned: 110.08 MB", "Data read: 109.50 MB (ratio 1.01:1)", "Time: 37.113 sec (0 m 37 s)", "Start Date: 2021:09:09 18:47:18", "End Date: 2021:09:09 18:47:55 " ] } ] } Is there a way to accomplish getting only stdout_lines in my report? I tried with grep in the shell command but failed
