`make k8s-up` - `Unable to convert config value for key 'integrations.github[0].apps[0].appId' in 'env' to a number`

[mathieu-benoit]

To continue with #73, we need to fix the issue below:

Error: Failed to instantiate service 'core.urlReader' for 'catalog' because the factory function threw an error, Error: Unable to convert config value for key 'integrations.github[0].apps[0].appId' in 'env' to a number`

After running make k8s-up, doing kubectl logs -l , getting this:

/app/node_modules/@backstage/backend-app-api/dist/wiring/BackendInitializer.cjs.js:264
      throw new AggregateError(initErrors, "Backend startup failed");
            ^
