Where do I find my Minecraft error log?

Open your game profile folder. Copy a file from crash-reports or logs/latest.log. Exit Code 1 alone does not explain the crash.

Where is my log sent?

Analysis runs in your browser. Your log is not uploaded to DEPTANA, stored in settings, or included in a shared URL. The text limit is two million characters.

Does a match prove the cause?

Diagnostics checks known error signatures. A match suggests what to inspect; it does not prove the sole cause. If no rule matches, the tool says so.
