Automation copy value from a custom field

[AldoCauchiSavona]

In our situation, the user is not allowed to set the priority in the portal via the Jira Priority field, but is given a different custom e field single select list where a subset of the Jira priorities are provided.

On issue creation, I am doing an automation rule to copy the user set value from the custom field to the Jira Priority field.

In the edit issue action, unless I'm mistaken I can choose the custom field to copy the value from, but I only get 'Copy priority from current issue'. I chosen Priority as the field to set, but instructing the action from where to copy the value from i'm not seeing.

Do I need to do the value change via JSON in the More Options JSON text are? If so, could you please give me a clue of how to do this because my JSON did not work (invalid JSON error), which currently is:

{"fields":
 {"Priority": "{{triggerissue.fields.customfield__10259.id}}"
 }
}

Hello @AldoCauchiSavona 

You don't need to use JSON for this. Simply start typing in the smart value for the source field.

After typing in the smart value you need to click on the space below the field where it says Smart value '{{ to get it to actually keep the smart value you entered.

I get no option to set the field as a text, what i get is like this, or as Set where I m given a list of priorities to choose from.

You need to click on the ... and choose SET.

That will change the display to something like this, showing an actual Priority value.

Then click in the field where the priority value (i.e. Highest) is shown and the full list of values will display.

Then start typing the smart value.
