SyntaxError: Unexpected token u in JSON at position 0 when using chaining operator in store.map #88

Versions

effector: 22.2.0
effector-logger: 0.13.4
node: 14.19.1

Reproduction

Codesandbox (react + effector): https://codesandbox.io/s/serene-frog-rvcke7?file=/src/App.js

Steps to reproduce:
1. Open sandbox repro
2. Type some player name into input
3. Click set player name
4. Open console and you'll see this error: SyntaxError: Unexpected token u in JSON at position 0
What is expected?

Error is not expected because when I'm using createStore and createEvent from 'effector' - there is no error.

Important

I observe this error only when using the chaining operator ?. is store.map. For example, if we change this line: const $playerName = $player.map((player) => player?.name); to const $playerName = $player.map((player) => player ? player.name : null); - there is no error

Issue is not reproducing at the latest effector-logger and effector versions https://codesandbox.io/s/billowing-feather-7hy6wr?file=/src/index.js

As of the recent '0.14.0' release, 'effector-logger' no longer includes 'effector-inspector' and integration with redux-devtools, so all related issues, including anything involving JSON.stringify, are gone.

See the release notes for details https://github.com/effector/logger/releases/tag/v0.14.0
