@empirica/core@1.9.0

Minor Changes

• cd48506: empirica export could fail with a "Premature close" error (t [CombinedError]: [Network] with empirica export #474). This seems
  to be originating from a bug in the node-fetch package, which is used to
  polyfill fetch in Node.js. This upgrades Node.js to v20+, which includes
  native fetch support. We still have the cross-fetch polyfill for projects
  that have not updated to Node.js v20+ yet. Export uses a vendored project which
  has been updated to use the latest Node.js version, so it does not require the
  entire experiment to be updated for it to use Node.js v20+.

  See the following issues on node-fetch for more details:
  Malformed chunked response detector creates false-positive ‘premature close’ errors when HTTP Agent involved node-fetch/node-fetch#1767
  Getting Premature close errors unexpectedly but very reliably in specific circumstances node-fetch/node-fetch#1576

Patch Changes

• b32b95a: Scoped objects should never be missing under EmpiricaContext. Some have reported
  player.stage or player.round being undefined, for example. This fix also
  more thoroughly checks that all expected objects (not only scoped objects) are
  always present.
