Steps to Reproduce and Observed Behavior

// foo.zig
const bar = @import("bar.zig");

:e bar.zig in nvim

thread 22260 panic: attempt to unwrap error: FileNotFound
error return context:

    try server.document_store.openLspSyncedDocument(document_uri, notification.textDocument.text);

                                                                  ^

this might be a bug in nvim, it seems pretty odd for it to do what its doing, but ZLS shouldnt be crashing because of it. i also managed to reproduce this in zed with the exact same steps

Expected Behavior

dont crash perchance

Attach ZLS log output
