Loopback-next: AssertionError [ERR_ASSERTION]: The binding selector must be an address

Created on 5 Feb 2020  ·  20Comments  ·  Source: strongloop/loopback-next

I've just done an npm upgrade and cannot start or build.
Note this is an lb3-mounted app. I never could get any of the migration to succeed (as of the orig port to lb4).

Node: v12.14.1

I can reproduce the problem now.

One workaround is to run npm dedup so that @loopback/context is only installed at root level.

@CNSKnight, from your above screen cap, I realized that the @loopback/context has upgraded from 1.x to 2.x. Could you please take a look at how to deal with the breaking changes https://github.com/strongloop/loopback-next/blob/master/packages/context/CHANGELOG.md#200-2020-01-27?

Can you run npm ls @loopback/context to see if you have other versions of @loopback/context?

BTW, try to upgrade using lb4 update after installing the latest version of CLI with npm i -g @loopback/cli.

Am getting a build but start throws:

What did you see for npm ls @loopback/context? You might have two different versions in the tree.

raymondfeng picture raymondfeng on 6 Feb 2020

In my case it is

stanils picture stanils on 6 Feb 2020

The old version @loopback/[email protected] is causing the problem. Please run npm i @loopback/[email protected] to make sure all versions are the same.

raymondfeng picture raymondfeng on 6 Feb 2020

@CNSKnight Please run rm -rf node_modules followed by npm i. Your stack trace shows there is an older version of @loopback/context is still inside @loopback/core/node_modules.

raymondfeng picture raymondfeng on 6 Feb 2020

Having the same issue after updating the dependencies today. Already tried removing the node_modules and re-installing all dependencies. npm ls also shows only Version 2.1.0 of @loopback/context is installed in the project

Any update on this, it's broken my deployment.

@baswag @rajanmishra Can you post the stack trace? If you have a simple project to reproduce the issue, please share.

What’s your node/npm version? On what OS?

We fixed this for our project by:

  • Deleting any yarn.lock and package-lock.json files you may have
  • Using the CLI to perform lb4 update

This is how my npm ls @loopback/context looks like now, but it still doesn't work
I have deleted the package-lock, node-modelus, and run a npm i with loockback/context version as 2.1.0.

Please upgrade to @loopback/[email protected]. The most reliable approach is as follows:

  1. npm i -g @loopback/cli
  2. Go to your project
  3. lb4 update
