Error when attempting to link records

Hello again,

I am receiving an 404 error inconsistently on a new scenario. (see below)

I have checked the data and there is one record I am searching for and one value in the field I am trying to use as a link in the linked record field in my destination table. On some records, the scenarios runs fine, others I see this message.

Any suggestions would be great - thank you!
