I am trying to create a question type for MongoDB (queries only using mongosh connecting to a static database). When I try to connect, I get the following error:

***Run error***
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Traceback (most recent call last):
  File "__tester__.python3", line 40, in <module>
    output = subprocess.check_output(['mongosh', "commands.js"],
  File "/usr/lib/python3.10/subprocess.py", line 420, in check_output
    return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
  File "/usr/lib/python3.10/subprocess.py", line 524, in run
    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['mongosh', 'commands.js']' died with <Signals.SIGABRT: 6>.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "__tester__.python3", line 45, in <module>
    raise Exception("mongodb error: " + str(e))
Exception: mongodb error: Command '['mongosh', 'commands.js']' died with <Signals.SIGABRT: 6>.
