Config:
"magento/product-community-edition": "2.3.3"
"PWA Studio": 4.0.0
Magento Core and PWA studio are in separate servers.
when running yarn build in PWA studio folder, i face this issue :
yarn run v1.22.10
$ yarn run build:prod
$ yarn run clean && yarn run load-env && webpack --no-progress --env.mode production
$ rimraf dist
$ node ../pwa-buildpack/bin/buildpack load-env --core-dev-mode .

at process._tickCallback (internal/process/next_tick.js:68:7)after some debugging, i found out that the error happens during webpack bundling, at this line :
const mediaUrl = await getMediaURL();
so i decided to test if i can do a request to my backend from PWA studio server, and this command worked successfully :
curl -H 'Content-Type: application/json' -X POST -d '{"query": "query {storeConfig{ id secure_base_media_url} }"}' https://********/graphqlthe query worked also in Altair GraphQL client.
last thing to mention, the build was successful when using the default backend as MAGENTO_BACKEND_URL env.
i tried to list all my debugging step, any help would be appreciated .
