Automation for JIRA to clear a field value


Please help to create an automation that clears a fields value using Automation for JIRA.

Hi Andrew,

I don't know your full use case but note that there are out-of-the-box Jira workflow post functions that can clear a field.

I found that, if you are doing an automation rule where the trigger is the changing of the value of a field, leaving date fields blank to clear them does not work.

Instead, I have to use {{clear}} trick:

Hi Mike,  What "{{clear}} trick"?  The given link provides no details.

I need to clear custom date fields "Target start" and "Target end" (created by Advanced Roadmaps), which are not visible in the field dropdown, hence must use the Additional Fields section.

Actually, after some trial and error, this appears to work:

    "fields": {
        "Target start": null

Hey Andrew, 

Thanks for reaching us. I'm from Automation for Jira team :)

It seems that you're trying to clean the custom field Baseline end date, right?

So, can you try to remove the additional field configuration?

Then, you'll need to keep this field empty, and with this configuration, your field will be empty.

Have a nice day!



Hi Chris,

I stumbled upon this issue, because I have the same use case:


Unfortunately, the solution you suggest does not work for me:

Any ideas on how to solve this?

Kind regards

Turns out: The problem in my case was that the Actor did not have "Edit issue" permission. :)

Now that I've given it this permission, I can confirm that your suggestion works.

Is it possible to do this for the Resolution Field? I'm trying to clear it when reopening an issue but all of the suggestions I can find don't appear to work:

This is currently what i have but it does not work.
