An error occurred while resolving packages:Project has invalid dependencies:com.needle.engine: Request [GET https://packages.needle.tools/com.needle.engine] failed because it lacks valid authentication credentials
A re-import of the project may be required to fix the issue or a manual modification of Y:/Rsm/_unity/DigitalTwin/Packages/manifest.json file.
Hi Михаил, it sounds like your project is failing both to resolve the Needle Engine package and to run the npm install command properly. Here are a few suggestions to try:
• The package error (“Project has invalid dependencies: com.needle.engine… lacks valid authentication credentials”) indicates that your manifest (located at Packages/manifest.json) is referencing a pre-release version (2.61.0‑pre) that now requires valid authentication. Since you mentioned the project is from 2.55‑pre, it’s possible the dependency got updated. Check your manifest file and either revert the version to one you know worked (like 2.55‑pre) or ensure you’re logged in/have the necessary API token to access the package from packages.needle.tools.
• The npm install error (“Win32Exception… Incorrect folder name specified”) can sometimes occur on Windows if the project is stored on a drive or folder that doesn’t fully support symbolic links. Make sure your project’s drive (in your case Y:/Rsm/…) is formatted as NTFS—not exFAT or FAT32, which can cause such issues (see our FAQ (docs/faq.html)).
• Try re-importing the project. It can help to delete the Library folder or use the re-import option within Unity to clear out any cached package data.
If you continue to see these issues, please verify your Unity version and consider using Unity’s “Copy Project Info Into Clipboard” feature. That extra detail can help pinpoint whether the authentication requirement for com.needle.engine has changed or if there’s a system-specific path issue.
Let me know if these steps help or if you can share more details so we can further troubleshoot the problem!
