The following advanced JSON block is not working if the subtask has the default values set on creation. It shows success but it doesn't work, the values are not copying and keeping the default values. The automation using this JSON works though if you update the parent, then the values are copying to sub-tasks.
the select cascade field is common for other projects so I don't want to change the default value for subtasks
{
"update": {
"Sample Cascade": [
{
"set": {
"value": "{{triggerIssue.fields.Sample Cascade.value}}",
"child": {
"value": "{{triggerIssue.fields.Sample Cascade.child.value}}"
}
}
}
]
}
}
