I get the exact same error. I have also added my .env file and set all env variables accordingly. Can you please check that? @Franpastoragusti

yarn upgrade --latest

@AppBankDigital, @cnadolny2s You're right, there are some issues on these external library versions. If you update them, you'll solve the problem.

to fix this issue replace "react-scripts": "^3.x.x" with "react-scripts": "^3.4.1" and remove node_modules then npm install again it will work Regards
