Grader Export Cell Fails

[bdsomer]

Describe the bug
When attempting to run the grader.export cell at the bottom of an Otterized notebook, I get the following error:

Running your submission against local test cases...

To Reproduce
Create a simple notebook with a question that has a test, like so:

{
 "cells": [
  {
   "cell_type": "raw",
   "id": "674ecf9b",
   "metadata": {},
   "source": [
    "# ASSIGNMENT CONFIG\n",
    "export_cell:\n",
    "    pdf: false"
   ]
  },
  {
   "cell_type": "markdown",
   "id": "7b205b0b",
   "metadata": {},
   "source": [
    "# Example Test"
   ]
  },
  {
   "cell_type": "raw",
   "id": "ac2958b0",
   "metadata": {},
   "source": [
    "# BEGIN QUESTION\n",
    "name: q1"
   ]
  },
  {
   "cell_type": "raw",
   "id": "1fdf7774",
   "metadata": {},
   "source": [
    "# BEGIN SOLUTION"
   ]
  },
  {
   "cell_type": "code",
   "execution_count": 1,
   "id": "9f18a9ca",
   "metadata": {},
   "outputs": [
    {
     "name": "stdout",
     "output_type": "stream",
     "text": [
      "hello world\n"
     ]
    }
   ],
   "source": [
    "print('hello world')"
   ]
  },
  {
   "cell_type": "raw",
   "id": "48d1ffa3",
   "metadata": {},
   "source": [
    "# END SOLUTION"
   ]
  },
  {
   "cell_type": "raw",
   "id": "5b509cca",
   "metadata": {},
   "source": [
    "# BEGIN TESTS"
   ]
  },
  {
   "cell_type": "code",
   "execution_count": 2,
   "id": "a5ad319f",
   "metadata": {},
   "outputs": [
    {
     "data": {
      "text/plain": [
       "True"
      ]
     },
     "execution_count": 2,
     "metadata": {},
     "output_type": "execute_result"
    }
   ],
   "source": [
    "True"
   ]
  },
  {
   "cell_type": "raw",
   "id": "d7690fb8",
   "metadata": {},
   "source": [
    "# END TESTS"
   ]
  },
  {
   "cell_type": "raw",
   "id": "a60f8819",
   "metadata": {},
   "source": [
    "# END QUESTION"
   ]
  }
 ],
 "metadata": {
  "kernelspec": {
   "display_name": "Python 3 (ipykernel)",
   "language": "python",
   "name": "python3"
  },
  "language_info": {
   "codemirror_mode": {
    "name": "ipython",
    "version": 3
   },
   "file_extension": ".py",
   "mimetype": "text/x-python",
   "name": "python",
   "nbconvert_exporter": "python",
   "pygments_lexer": "ipython3",
   "version": "3.11.4"
  }
 },
 "nbformat": 4,
 "nbformat_minor": 5
}

Then, use otter assign to generate the student version of the notebook. Upon running all of the cells in the student version of the notebook, the aforementioned error occurs.

Expected behavior
The notebook exports properly, with no error.

Versions
Python 3.11.4, otter-grader 5.0.2
