This code looks all right - org-agenda-prefix-format placeholders are
evaluated with current buffer being Org buffer (normally).

May you try to run M-x debug-on-entry RET display-warning RET and
try triggering the warning? Then, you will see a backtrace with the full
information about where the warning is triggered.

(you can later disable the debugger via M-x cancel-debug-on-entry RET RET)
