When trying to build a React Native application, we get the following warning.
warn Package blockstore-core has been ignored because it contains invalid configuration. Reason: Package subpath './package.json' is not defined by "exports" in /home/arnold/Projects/ltonetwork/universal-wallet/node_modules/blockstore-core/package.json
This can be solved by adding an export to package.json
"exports": {
...
"./package.json": "./package.json"
}
