Some users may run into issues when using the VRChat SDK or the Unity Editor itself.

Common SDK errors

There are errors that may occur within the VRChat SDK, and this section aims to identify and troubleshoot these issues.

Common troubleshooting solutions

Update SDK/tools

In many instances, checking for updates for the SDK can help fix many issues. You should keep your SDK updated to the latest release version if you are experiencing any issues. The same goes for any additional tools one may be using, outdated tools could cause unpredictable issues.

The VRChat Creator Companion (VCC) aims to streamline management of keeping Unity, the VRCSDK, and packages updated. Though, some external packages may require manually downloading updates, and re-importing them into VCC or your Unity projects.

Remove newly added assets/tools

If issues arise, shortly after installing a certain tool or package, try removing the file from the project, and restarting Unity to see if it fixes the issue. Some tools may be outdated, or may not support or be compatible with the current SDK or Unity version. In cases such as this, inform the creator of the tool, or find an alternative.

"Missing Credentials" when uploading

For advanced options, see also Guides:Connection issues.

If you're logged into the SDK, but receive an error for missing credentials when uploading, this could often due to using a VPN service. If you have a VPN service enabled, try turning off your VPN, and it should fix the issue. This can also occur while using software such as Cloudflare's WARP, which acts similarly to a VPN. In the case of WARP, disabling it, or switching to regular 1.1.1.1 without WARP will fix the issue.

"Avatar Failed Upload" when uploading

This is a generic error.

Occasionally, when uploading, the SDK might generate an Avatar ID that is already in use, or the creator might not have removed the Avatar ID from the blueprint. This issue can also occur if you do not own the Avatar ID.

Common Unity Editor issues

There are errors that may occur within the Unity Editor, and this section aims to identify and troubleshoot these issues. Make sure you are using the current Unity version, that is compatible with VRChat.

Common troubleshooting solutions

On some occasions, the Unity Editor will break, for no discernable reason. There are numerous methods that can fix most issues.

Reset Layout

If you are having issues, related to Unity's user interface, such as the "configure" button in the avatar rig tab; or other oddities when selecting assets, such as the Inspector turning blank, resetting your layout in the top-right dropdown can fix most issues.
