Replacing the error thrown when using .firstValue

[mahyarwd]

Hey guys!
I'm currently changing some promises to use .firstValue(where:) to find matching element and this works well. My only issue is that i want to replace the standard error "PMKError.emptySequence" thrown to my own error for better clarity.
I have tried chaining the .firstValue with a .recover but that doesnt seem to work.

Any ideas on how i can achieve this?

Thanks in advance!
