Hi Osman Kael,
Thanks for contacting Syncfusion support.
We are glad to hear that your reported issue was resolved in that way. And, we found that we have provided the code snippet for compiler configuration from generated ‘compilerconfig.json.defaults’ instead of root ‘compilerconfig.json’ file. Sorry for the inconvenience. We have logged a documentation correction task for this syntax error and it will be available in live in our upcoming second patch release which is expected to be rolled-out in the first week of March, 2020. Until then we appreciate your patience.
Regards,
Banupriya
