Disable CORS for local deployments

[priamai]

Hello,
we need to find a way to disable CORS for local deployments otherwise it's impossible to use.

Hi guys! I guess it's not CORS, but a backend problem. Can you send me the call Response on the network tab, please?

Hmmm it is weird, but I do believe is a simple CORS issue:

There is no response from server because is blocked.

But from the docker logs:

showwhy-frontend-1        | @showwhy/webapp:start: Entrypoint main 24.3 MiB (20.5 MiB) = main.ff838458f89b87c18d99.js 24.3 MiB main.04dc6812f929d7051131.hot-update.js 360 bytes 2 auxiliary assets

showwhy-backend_api-1     | INFO:     192.168.2.23:43620 - "OPTIONS /api/discover/pc HTTP/1.1" 400 Bad Request

The error is a 400 which matches the browser info:

Request URL:

Request Method:

Status Code:
400 Bad Request
Remote Address:

Thanks for the images! I'm trying to build it here again because up to this day I couldn't get the same error, I'll check here

Thanks a lot so this is the command I used:

yarn install
yarn build # or yarn force_build
yarn start

This is the only file I modified, the package.json I changed the host to my local domain:
