IntelliJ Plugin for PhpStorm: "WorkspaceFileIndex is not initialized yet" error during plugin execution

I'm developing an IntelliJ plugin for PhpStorm, and I'm encountering an error during the execution of my plugin. It occurs every time I run my plugin. Could someone help me understand the root cause of this error and how to resolve it?

The error message I'm getting is:
