When I hit the rename dialog in a typescript file when the file is empty or in a context where I can't open this dialog, the dialog which comes up is empty and I can click on preview or refactor. First it shows me this error

Module LSP Client threw java.lang.NullPointerException. Please report a bug against LSP Client module and attach your var/log/messages.log.

and second an Unexpected Exception was thrown:

Steps to reproduce
* Open a clean instance of NetBeans 12.4
* Create an HTML5 project and let everything to default
* Right click and choose New -> Other -> Other -> empty file and name it foo.ts
* Open the file and hit ctrl + r for rename
* An empty rename popup opens
* Click on preview or refactor and see exception.

Was was expected
That I can't open the rename dialog due to a missing context and I need to see the info, that I can't rename here due to the missing context as in other parts of the IDE.
