Usual "concatenate trick" to solve "Cannot assign list of string to string" doesn't work

UPDATE: I realised I don’t need a separate Find records step, I can do a direct Update record. There both the lookup and the formula version work. 

Would still like to understand how to deal with the Fin records, for future reference.

To turn a lookup field into a string, you would need to append an empty string of text like this:

{Lookup Field} & ""

Yeah that’s because ‘Find Record’ is returning an array, not a single result

I usually add a ‘Run a script’ step to convert it into a string / number as needed

​@Alexey_Gusev has a simpler nocode workaround using an ‘Update record’ step and updating nothing for the record in question, and then using the ‘Update record’ step’s output for the next Find Record step.  You’ll need to have a field that you’ve set up specifically for this though so that you can update it as a blank though I think?  Alexey, apologies if I’ve misunderstood what you meant; any errors are my own!
