I'm getting this infamous error. I've read through some posts but I have'nt seen any get it from a page layout. Also most don't get an ID in their error message I do:
layouts/Opportunity-FS Renewal Capture.layout -- Error: duplicate value found: unknown duplicates value on record with id: 0Jo4C0000003wvl
I have soql and sosl queried for the Id but found nothing. Where else can I look? If the error message contains the ID surely it exists somewhere in my org, right ?
