Another way to reproduce the error "Uncaught Error:Invalid start offset:-1"

1.Open the editor
2.Add a text
3.Go the next line add a bullet list with a text
4.Add indentation to that item
5.Press enter go to the next line then add indentation to the second empty bullet item
6.Press enter to go to the next line
7.It actually takes the cursor to the end of first bulleted item
8.Press delete until all the bullets comes in the same line.
9.The cursor then moves to the end of the first line of step 2
10.Delete that text
11.Now place your cursor at the end of series bullets press delete to delete it

A. you will get the error:Uncaught TypeError: Cannot call method 'getOffset' of null

B. If you again press delete , you will get "Uncaught Error:Invalid start offset:-1"

C. if you press undo then redo, you will get "Uncaught Error: Unbalanced input passed to document"

D. if you attempt to save the page, you will get "Uncaught TypeError: Cannot set property 'lastOuterPost' of null"

Steps 1-7 are as expected. I don't understand step 8, as after 7 there is only one double-indented bullet item.

I've reproduced the steps in the video but I don't get an exception. Can you try again with the latest code.

Yes , I can still reproduce it.Attaching the screenshot.
Are you getting the error:Uncaught TypeError: Cannot call method 'getOffset' of null ?

I can't reproduce this problem as written (Chrome here too), but there is some funkiness related to being able to split some mutli-depth bullet list items oddly.

Giving steps to reproduce again:

1.Open a completely new page with VE
2.Add a text
3.Click on Bullet list icon from the toolbar
4.Add indentation to that line
5.Go to the next line (Adds a second bullet)
6.Add indentation to this second bullet line too
7.Go back to the first bullet point and delete the text
8.Go back to end of the second empty bullet point
9.Press Delete(this will bring all the bullet points in one line)

After this step you will get the error:Uncaught TypeError: Cannot call method 'getOffset' of null

If you press Delete again it will show error Uncaught Error: Invalid start offset: -1

Looks like this was done as part of the "handle enter" re-write.
