TypeError: Cannot read property 'replace' of undefined about orca

[DimiMikadze]

Hi, I think that happens because, the app isn't able to find environment variables. e.g. REACT_APP_WEBSOCKET_API_URL

[NickNck]

HI thanks for the quick reply. May i ask why does this happen? For some reason i also got a string error with the env variable for mongodb link so i had to manually enter the string within mongo.connect() and it worked...so im assuming i have to do something similar for websocket api url?

[NickNck]

So how can i solve this please? Very new to javascript and react

[DimiMikadze]

You need to learn what environment variables are and how to use them in Node.js ecosystem. After learning it, read repositories readme carefully and you'll be able to solve this issue.
