Set custom field to empty in automation

I'm having some difficulty clearing a custom field in automation.

When I set it to clear as follows, it isn't changed:


The same with trying in the additional fields (one at a time):

"update" : {
"TmpField" : [{"set":"" }]

{ "fields" : {
"TmpField" : null

{ "fields" : {
"TmpField" : ""

Among other things. I can set it to a new value, and even to things I wouldn't expect a single line field to accept such as "\n" 

I'd prefer not to use a transition post function (as this is intended to be cleared when transitioning from a status and there are various destination statuses) but that's seeming like my only option.

Any thoughts on how to clear this field using automation?

Hi Iona,

What does the log tell you when it fires but doesn't clear the value?

Kia ora John

It said "Issues edited successfully [ISSUE KEY]"

I've just tried deleting and remaking the custom field and it works with the new one, so I'm not sure what was happening with it before.

Im trying to cleat the 'Resolution' field on my end. Doesn't look like mine is working properly. 


This is what I've got. Would you be able to help?

Hi Hoc - it is always better to create new questions in the community than to add to old ones. Please post a new question so more people will see it, and we can answer your questions in the new. Thanks!

Had the same issue recently. To clear an insight field using automation you need the following json:

     "update" : {
           "customfield_xxxxx" : [{"set": []}]

As Insight fields are stored as an array, you need to populate the field with an empty array.
