Custom actions doesn't work

Describe the bug Custom actions doesn't work. I've used it some time ago, now I can't.

Here is the part of the template Mingo gives you:

async function run() {
    await projects.updateOne(
      {_id: CurrentDocument._id},
      {$set: {
         field: null
      }}
    );
    return 'Done';
  }

Screenshots

Desktop (please complete the following information):

Mingo version: 1.13.5
OS: MacOS Sonoma 14.2
