Undefined type in generated file

[hheld]

I'm getting the following error in the generated file bindata_assetfs.go: undefined: AssetInfo

This happens in this generated function:

func assetFS() *assetfs.AssetFS {
    for k := range _bintree.Children {
        return &assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir, AssetInfo: AssetInfo, Prefix: k}
    }
    panic("unreachable")
}
