Warning in production caused by babel react optimisation

I’m running an erb app packaged in an appImage and it seems that react is not running in production mode because it showing warning about unique key prop. Normally this type of message don’t show up in production mode.

I’m not able to reproduce the same behavior with the command DEBUG_PROD=true yarn build && yarn start. I have several pages my app and some of it shout this type of message.

After investigating a little it seems this “issue” with babel transforms is related
