Jest tests aren't working

[grigory-bogush]

Compilation of the project works fine but as soon as try to run tests it fails with an odd syntax error that is not present when the craco-esbuild is disabled in craco.config.js. Perhaps there is a way to add this plugin for build & start leaving tests as is? Any help would be appreciated.

yarn test
yarn run v1.22.10
$ craco test --watchAll=false

hey @grigory-bogush did you have any lead on why transformation fails? 🤔
