What should I use as smart value in automation to get previous value of a custom field of type date?

[Enchanted Realms]

I am trying to create an automation which activates when a custom field of mine of type Date is changed under certain conditions. The required result is for this custom field to have the old date value set before it changed to the new one. Please help as I am currently using :  

{{issue.fieldChange.fromString}}

Hi @Enchanted Realms 

Welcome to the community!

Please check the article Automation smart values - issues {{changelog}} 

i.e

{{#changelog.CUSTOM_FIELD_NAME}}
{{fromString}}
{{/}}

Hope this helps!
