Can't publish project to Hubs

[TuxMiester]

It shows "cannot read properties of null (reading 'animations'). How do I fix this ?

I also just got this error - "cannot read properties of null (reading 'array')" -

JS error was:

EditorContainer.js:862 TypeError: Cannot read properties of null (reading 'array')
    at dt._combine (MeshCombinationGroup.js:223:50)
    at dt.combineMeshes (MeshCombinationGroup.js:151:34)

I was able to resolve this by deleting one object (an image) from the scene that I had recently added. Then i re-added it and unchecked "combine" since i thought MeshCombinationGroup.js was a clue. That worked.
