Requirement:
Nunjucks code snippet to retrieve the date, time when the issue was moved to a specific status.
Solution:
If the issue was moved to the desired status multiple times:
Case 1: Code to get the date, time when the issue was last moved to the desired status:
{{ issue | fieldHistory("status") | filter(["to_string","STATUS_NAME"]) | last | field("date") | date }}
Case 2: Code to get the date, time when the issue was first moved to the desired status:
{{ issue | fieldHistory("status") | filter(["to_string","STATUS_NAME"]) | first | field("date") | date }}
Replace STATUS_NAME with the desired status name(as-is → case sensitive and no trailing/leading white spaces)
This Nunjucks code can be added in workflow post-functions (and Actions)
