Consistent HTTP 422 errors when publishing assets to GitHub release

See original GitHub issue

👋

We’re using semantic-release/github plugin to publish assets to each release we make with semantic-release.

The release configuration is as follows:

{
  "prepare": [
    "@semantic-release/npm",
    {
      "path": "@semantic-release/exec",
      "cmd": "npm i -g pkg && pkg ."
    }
  ],
  "publish": [
    "@semantic-release/npm",
    {
      "path": "@semantic-release/github",
      "assets": [
        {
          "path": "./snyk-linux",
          "name": "snyk-linux",
          "label": "snyk-linux"
        },
        {
          "path": "./snyk-macos",
          "name": "snyk-macos",
          "label": "snyk-macos"
        },
        {
          "path": "./snyk-win.exe",
          "name": "snyk-win.exe",
          "label": "snyk-win.exe"
        }
      ]
    }
  ]
}

The assets are being published as expected, however the plugin fails over a 422 response from GH:

I appreciate the fact this may be on GH side, opened a support ticket with them, will update here once I hear back.

Wanted to document the issue here, maybe there’s more context?
