Advaned compare first value - multi select option

[salva garcía raro]

Hello! While trying to set up an automation using an advanced compare step, I get the following error: 

Error while parsing additional fields. Not valid JSON. 

It seems I can't compare the values from the option list with the selected option. 

How to achieve this? 

This corresponds to a custom field with 2 options: 

[Marc - Devoteam]

Hi @salva garcía raro 

If you use, the following.

{{issue.customfield_10039.value}} or other option {{issue.<name of the field>.value}}

Does the compare work, using any of the 2 options?
