}
The problem occurs when I build production app. When trying to launch the server by calling "node index.js" - I'm getting error:
Error: Could not find package.json up from 53263
By digging some source code I found this line of code in index.js of prometheus-api-metrics:
require('pkginfo')(metricsMiddleware, { dir: Path.dirname(module.parent.filename), include: ['name', 'version'] });
Apparently, when using "commonjs" - module.parent does not exist and it is causing a problem.
Does anyone have any solution for this?
