Updating custom field of subtask with custom field value from parent task - Clickup

[Clemence1]

Hi there! I am trying to build a scenario and found some closed threads on this but couldn’t figure it out… so here I am.

Scenario layout so far:

Module 1: triggered upon task creation (works)

Module 2: gets information from created task (works)

Filter: checks if new task has a parent task (works)

Module 3: gets information from parent task (works)

Module 4: takes value from custom field of parent task and applies it to custom field of subtask (does not work).

error I am getting:

Current layout of Module 4:

I’ve tried without the “=” sign, I’ve tried putting the “6. Custom fields: PVG Project Number” down in the “Custom Fields” before the “=” sign, etc. I’ve tried a variation of things. I’m a little stumped as to what the “Task ID” is supposed to be up top too..

I’d appreciate any support! Thank you!

I now understand the “=” is a no go so I had AI help me but I’m still getting the same error. My Custom Fields area now reads:

[{“id”:“bfc548fe-7c9a-47bb-b13c-75e99dee047b”,“value”:“{{7.custom_fields.PVG Project Number}}”}]

The “id” number comes straight from my module 6 output, and the “value” is from my module 7 output.

Alternatively, I’ve tried untoggling the “map” option by the Custom Fields parameter and entering things on my own.

This gives me a different error:

Okay folks, I figured it out. I am posting here in case anyone else is struggling and can’t find solutions in the other closed threads.

Here goes!
