Improve error message when snapshot file read fails #1344

Closed Egorand closed 6 months ago

Egorand commented 6 months ago

Fixes #1343.

Stack trace example:

java.lang.NullPointerException: Failed to read the snapshot file.

    If your project uses git LFS, it's possible that it's misconfigured on your machine and
    Paparazzi is trying to load a pointer file instead of the real snapshot file. Follow git
    LFS troubleshooting instructions and try again.
