There is currently no link between elements

Error message

There is currently no link between elements '{0}' and '{1}'

What it means

Internal lookup guard in AssetDependencies.GetLink: a link lookup (in, out, or broken-out) was requested for an AssetId that has no recorded AssetLink in the corresponding dictionary. Callers asked for a dependency link that was never registered between the two elements.

Solutions

1. Verify the dependency link exists (e.g. via ContainsLink-style checks) before querying GetLinkIn/GetLinkOut
2. Register the link first with the builder API that populates the link dictionaries
3. Ensure asset ids passed are the ones analyzed, not stale ids from a previous analysis pass

When it happens

Trigger: Thrown at sources/assets/Stride.Core.Assets/Analysis/AssetDependencies.cs:293 when the library encounters an invalid state.
