Some issues following ctx.ast.move_expression

[anguish-huihuang]

After using ctx.ast.move_expression, the original position has become null. May I kindly ask if there’s a way to remove these? I apologise for any inconvenience caused.

The above is the code I wrote for moving nodes.

This is the specific result of converting ternary expressions into if statements that I wrote. There are many unnecessary instances of null ? null : null; and I wonder if there’s a quick way to eliminate these redundant nulls. I apologise for bothering you during your busy schedule.

This is an expected behavior, what's your expected output?
