@Siprj thanks for looking into this and raising a PR, I noticed this a part of #1717 but got bogged down with other changes, I wonder re. the change if you could swap the variable to work as follows:

 const editsToUse = edits.documentChanges
            ? convertTextDocumentChangesToFileMap(edits.documentChanges)
            : edits.changes

It's a small change but the re-assignment using let is a little more verbose and this was the change I was gonna (eventually) propose in #1717 (which would help me out as it would reduce conflicts there

@Akin909 Done.
