Visual scripting automated build failure

Unity Engine

Hello,
I am trying to build a basically empty project with visual scripting.
Unity 2021.1.18f1
Visual Scripting 1.6.1
I can successfully build from the editor, but on our teamcity buildmachines I always get the following error:

InvalidOperationException: Trying to access plugin container before it is initialized.
at Unity.VisualScripting.PluginContainer.EnsureInitialized () [0x0001a] in /Applications/buildAgent/work/BLU/branches/visualScriptTest/ios/Library/PackageCache/com.unity.visualscripting@1.6.1/Editor/VisualScripting.Core/Plugins/PluginContainer.cs:349

I’m not sure I should submit a bugreport since it only happens on the buildmachine and I can’t repro locally.
Any suggestions as to why this happens and how to prevent that error are greatly appreciated.

For anyone who encounters this - I upgraded com.unity.visualscripting version to 1.7.3 and it properly builds now. The confusing thing is that Unity 2021.1 doesn’t show any version beyond 1.6.1, even though I have “show preview packages” turned on, so I had to do it by manually updating manifest.json.

I’m pretty sure you’re not seeing 1.7.3 on 2021.1 because they broke SubGraph serialization between 1.6 to 1.7 by renaming SuperUnits to SubGraphs. So 1.7.3 is what you get by default on 2021.2. Forcing the update on 2021.1 via manifest.json with an empty project worked fine on my end, though your mileage may vary.
