"com.intellij.openapi.vfs.VirtualFile.getPath()" exception #722

Open MihaMarkic opened 1 week ago

Not sure how I got this one (AFAIK it happened only once lately), but there it is. Using Rider 2024.2.7. HTH. Plugin 1.24.

java.lang.NullPointerException: Cannot invoke "com.intellij.openapi.vfs.VirtualFile.getPath()" because the return value of "com.intellij.openapi.vfs.VirtualFile.getParent()" is null

Can you see an INFO log that starts with "grammarFileSavedEvent" just before the exception (see Locating IDE log files)?

In theory VirtualFile.getParent() returns null when this file is a root directory, but that can't be right in our case, the plugin wouldn't analyze a root directory :/
