Im using a custom registry and when i'm running Npm Search command, the client is throwing the following error:

according to the stacktrace it is failing on format-search-stream.js:98 :

publisher: strip(data.publisher.username),

publisher field is new. i didn't found any official DOCS about it and there is no default value.
it's an unexpected and not documented breaking changes

in the code lines 5-17 in the above file, the example json is:

// This module consumes package data in the following format:
//
// {
//   name: String,
//   description: String,
//   maintainers: [{ username: String, email: String }],
//   keywords: String | [String],
//   version: String,
//   date: Date // can be null,
// }
//
// The returned stream will format this package data
// into a byte stream of formatted, displayable output.

someone can take a look and assist?

Expected Behavior

While running Npm Search, the client will return the package.
this issue is started to appears from npm version 10.6.0.

@wraithgar
you probably used npmjs. try to use another registry.
Im using jfrog artifactory.

I'm using a custom registry

Ah your custom registry returns a different search payload than the npm registry. We'll have to default that to "unknown"
