Reproducible on:

• Unity version: 2021.2.0b2 and 2021.1.13f1
• VS version: 1.7, 1.6

1. Create a new project (most probably a "new" project is not necessary but was the step that we could repro steadily)
2. Create a new custom node, right-click on Project->Create->C # script
3. Open the created script and copy-paste the following code and save

{code:java}
using Unity.VisualScripting;

public class MyNode : Unit
{
protected override void Definition() //The method to set what our node will be doing.
{
}
}
{code}

1. Regenerate Nodes from Edit->Project Settings->Visual Scripting
2. CReate a new Script graph
3. Click to open the fuzzy finder

Actual Outcome:

• The newly created node does not appear on the fuzzy finder
• The node does not appear on the nodes DB

Expected Results:
