What happened?

After getting the error in #473, I tried to export my data, and was not able to.

(I've been exporting by moving tajriba.json from the server to my computer, and it usually works this way)

Hopefully this should be fixed in the latest release. I could not reproduce it, but I have found an issue that looks suspiciously similar. See the release notes if you're extremely interested in the details. Otherwise, with the update, empirica export should be using the latest version of nodejs, which should fix this issue. Please let me know if it's not the case. You might also want to upgrade the version of node you're using in the experiment, though this has had limited testing so far (all tests pass, but I can't say for sure), so up to you. If you want to, you can change the "volta" section in server/package.json and client/package.json to:

  "volta": {
    "node": "20.10.0",
    "npm": "10.2.3"
  },
