Hello there, @Pirantul ,

Thank you for your interest in working with our products.
This is actually an error from the react-scripts package, here is the link to the mentioned issue: facebook/create-react-app#7753
To solve the issue, please run the following: npm i -E eslint@6.4.0.

Best,
Manu

I got a different error:

node_modules/eslint/lib/rules/no-octal-escape.js:41
                    /^(?:[^\\]|\\.)*?\\([0-3][0-7]{1,2}|[4-7][0-7]|0(?=[89])|[1-7])/su
                    ^

SyntaxError: Invalid regular expression flags

The recommended workaround does fix this problem aswell.
