Please, provide the details below:

Did you verify this is a real problem by searching [Stack Overflow

Yes. Several issues are not relatable to the current problem.

Tell us about the problem

Issues when compiling using local external module.

Which platform(s) does your issue occur on?

Android, didn't try in iOS yet.

Please provide the following version numbers that your issue occurs with:

• CLI: (run tns --version to fetch it) 3.0.3
• Cross-platform modules: (check the 'version' attribute in the
  node_modules/tns-core-modules/package.json file in your project) 3.0.1
• Runtime(s): (look for the "tns-android" and "tns-ios" properties in the
  package.json file of your project) 3.0.1 (android)
• Plugin(s): (look for the version number in the package.json file of your
  project) NO plugins

Please tell us how to recreate the issue in as much detail as possible.

Create an external local module, in my case it's just a module that does an HTTP Request (a "Login" module).
Add it to the package.json using "file:", like this:
"@hextra/core": "file:../condiviso/moduli/core"
run
npm install
run
tns debug android

Further notes:
If I run the application through the VSCode NativeScript extension, I don't get the error detail and the application runs properly, but the debugger is crashing:

JS: AssetExtraction: Can't remove previously installed assets in /data/user/0/org.nativescript.HextraMobileBase/files/app

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

See above.

Hey @briosheje ,
May I ask you to try to reproduce the same issue with latest CLI. We had some similar issues that we've resolved in our 3.1.x release.
I'm looking forward to hearing from you.

@rosen-vladimirov @dtopuzov Sorry, I had no time to test this until yesterday night.

I've re-delployed the app today and everything seems to be working fine now, the error somehow disappeared, thanks.
