### Check existing issues - [x] I've verified that this bug isn't described by any existing issues. ### Bug description Today snapcraft is having issues. I found that if I upload my package, it errors with a HTTP 500 but nevertheless the process exits with exit code `0`. This makes it difficult to use snapcraft in shell scripts for build pipelines and such. ``` $ snapcraft upload myproject_amd64.snap Uploading... 17744080/17744080 Issue encountered while processing your request: [500] Internal Server Error. Full execution log: '/home/michiel/.local/state/snapcraft/log/snapcraft-20260325-124413.959196.log' $ echo $? 0 ``` Expected behavior was to see a non-zero exit code ### Steps to reproduce Upload a snap to the snap store while snapcraft is having an outage ### Environment just uploading using snapcraft 8.14.4 installed as a snap ### snapcraft.yaml ```yaml ``` ### Log output ```shell 2026-03-25 12:44:13.960 Starting snapcraft, version 8.14.4 ... 2026-03-25 12:44:14.060 HTTP 'POST' for 'https://dashboard.snapcraft.io/dev/api/snap-push/' with params None and headers {'Accept': 'application/json', 'Authorization': '<macaroon>', 'User-Agent': 'snapcraft/8.14.4 ubuntu/25.10 (x86_64)'} 2026-03-25 12:44:14.188 Beginning to upload a file 'myproject.snap' with size of 17743872 bytes 2026-03-25 12:44:14.188 Uploading...
