Thanks for the report! The root cause checks out — for object-store FileIOs the single-arg `checkArgument(boolean)` in `asFileSystemIO()` does throw `IllegalArgumentException: null`. **question:** I can't quite square the "reproduces 100%" claim with the `io.exists()` guard right before the throwing line: ```java if (!io.exists(directoryPath)) return; // TableFileUtil:90 ... io.asFileSystemIO() ... // :95 — throws ``` For `S3FileIO`, `exists()` is a HEAD on the exact key, and `directoryPath` is a slash-less prefix (`s3://.../data`) → 404 → `false` → returns at line 90, never reaching 95. Verified on our own S3FileIO-backed catalog: a HEAD on the slash-less prefix key returns 404, and I couldn't reproduce the failure there. Could you share: 1. the exact `io-impl` + Iceberg version, 2. which object storage you're on (AWS S3, Ceph RGW, MinIO, etc.), and 3. whether a HEAD on the slash-less prefix key returns **200** in your env? Reaching line 95 seems to need `exists()==true` for that prefix, which looks storage/environment-specific rather than universal. -- This is an automated message from the Apache Git Service.
