Fixes #2622
I don't know the exact detail of the crash, but I find that tsc crashed because the
diagnostic.file
object is somehow missing aresolvedPath
field. Meanwhile, thefileName
field is always present. So I just added a fallback tofileName
in the patch.Maybe related: microsoft/TypeScript#54057
I only add it to the 5.0 branch because I haven't tested it on 4.x, so let's play it safe.
