Steps to reproduce:

1. Phorge at 67c0efdffb79d63ffcc15e07a0798f415a4e0845 , PHP 8.3.7.
2. Create a task list by manually attaching task IDs as integers: http://phorge.localhost/maniphest/?ids=1,2,3,4
3. See that it works - Phorge lists the tasks.
4. Create a task list by manually attaching task IDs as monograms: http://phorge.localhost/maniphest/?ids=T1,T2,T3,T4

Actual outcome:
A cryptic error message "Expected a numeric scalar or null for %Ld conversion"

plus log spam that I am not interested in.

Expected outcome:
A helpful error message

without log spam.
