sls deploy fails "npm install failed with code 1"

[afcode123]

Hi!

Sls deploy has worked fine in my project previously but now I am suddenly getting an error when running sls deploy. Any ideas how to fix this? Or how can I get more info on what fails with npm install? I tried to set SLS_DEBUG=* but the error message regarding npm error is insufficient.

Hello @afcode123 👋 It seems like the issue might be caused as a part of logic of serverless-webpack - did you try to look for resolution in the repository of that plugin?

[afcode123]

Thanks for the reply! you are correct, that seems to be the issue. I will try to look from there

[Ankitdet]

what is resolution ? I'm facing the same issue.

The serverless.yml file should contain:

custom:
  webpack:
    webpackConfig: 'webpack.config.js' # Name of webpack configuration file
    includeModules: false # Node modules configuration for packaging
    packager: 'npm' # Packager that will be used to package your external modules
    excludeFiles: src/**/*.test.js # Provide a glob for files to ignore
