# Typical errors

### 1. \[webpack-cli] ModuleNotFoundError: Module not found: Error: Can't resolve 'prosemirror-keymap' TIPTAP 

This error can occur when running "b2b:platform:build"

1\. Go into path: **custom/plugins/b2bsellerscore/src/Resources/app/b2b\_platform**\
2\. Install dependencies with this command: 

```
npm i prosemirror-schema-list prosemirror-history prosemirror-dropcursor prosemirror-gapcursor prosemirror-keymap prosemirror-commands
```

Afterwards it should be possible to build our b2b platform.

### 2. Alternative:

```
// Quickfix, use specific npm version (dockware.io)
source ~/.bashrc
nvm install 16.15.1
```
