Requests can not be exported to CSV when a title level request is present

Overview: when at least 1 TLR is created on environment, export of search results is not working. Error in console is following:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'firstName') utils.js
at dp (utils.js:41:11)
at RequestsRoute.js:986:26
at Array.forEach (<anonymous>)

at Generator.next (<anonymous>)
at Is (bundle.stripes7efba8e4f247f8293fbb.js:4312:165064)

Steps to reproduce:

1. Create at least 1 item level request

2. Create at least 1 title level request

3. Search/apply filters to return any results

4. Click “Actions” → “Export search results (CSV)”

Expected result: requests are exported to csv, file is downloaded

Actual result: no file is generated, no error appears on UI, “Export search results (CSV)” option is loading endlessly (need to relogin to perform action again)

Additional info: discovered on Sprint testing eureka env, no possibility to check the same on snapshot due to inventory crash

Behavior on eureka bugfest is a bit different, the csv is not generated only sometimes and when the TLR is present among the results list, the error in console says:

Failed to load resource: the server https://kong-eureka-bugfest-ramsons.int.aws.folio.org/circulation/pick-slips/a3cbfa53-3e36-4cbc-8213-85848623d73b responded with a status of 500 ()
