Unable to sum from multiple value into Story point estimate in Team Project

[Takei Vo]

Hi all currently i'm want to get the FE/BE/QA Story Point custom field and combine them into 1 for Story issue with this code for example:

{ "fields":
{ "Story point estimate": 
{{issue.customfield_10082.asNumber}}+
{{issue.customfield_10083.asNumber}}+
{{issue.customfield_10081.asNumber}} 
} 
}

after tried like leaving only 1 customfield, the Story point estimate only return 0 and i'm even did tried {{#=}} and {{/}} but it's still not work

Here the flow how i expected:
Epic -> Story -> Task -> Subtask

Task will have relate issue to Story and after the Task have assign FE/BE/QA either three of them, Story automation will start sum the number and show up on Story point estimate on Story issue

Then Story will push the estimate to Epic


Does anyone have any solution? Thank you.

Have every found the answer ? Since I am having the same issue but slightly differently.

What I want to achieve is as below :

Story ( Custom Field - Child Story Points Sum )

Roll up ( Add the story points from sub-task to Child Story Points Sum field in the Story )

Sub-task ( Story Points ).
