Automation: how to copy the last comment of an issue to a custom field in JIRA?

[Giorgio Crosali]

As the title suggests, I'm struggling to create the proper JSON script and I'm not allowed to use plugins

Hi @Giorgio Crosali 

You could use the built-in automation for Jira rules for this, such as:

• trigger: issue commented
• action: edit issue for your custom field, setting it to the last comment's body, or other contents.

Please look here for information about automation to get you started:

This is as far as I have gotten:
