Hi,
I am trying to create a new power Automate for handling work orders.
The concept is that on the creation of a work order in the work order table (cr318_sagemworkorders), it will create some records in a linked table (cr318_sdeworkorderpicklists).
I have a trigger on the cr318_sagemworkorders table

then later in the code I have a add new record on the cr318_sdeworkorderpicklists table:-

in the field for the link to the work Order I have put in the SageM Work Order unique ID

using the dynamic content:-

however when I run it I get the following error:-

but if you look at the work order data then this is the correct reference number, and it does exist.

I have also tried using the work order field and that came with the same error message (but with WO021113 instead)
When I have created the record manually and then looked that the Pick list table. it has that same reference code:-

it feels like I have made a simple mistake, but I can't find the flaw in my logic.
