## Ticket
910
## Changes
- Change the "message" from a generic "tus-upload" to more specific ones like "tus: failed to resume upload". These are grouped as "Events" in sentry, so we can isolate and search for them easily.
- Pass more info to Sentry (previously only available from Slack). It is still good to send to both, since some browsers block Sentry even without blocker extensions.
- Reduce verbosity of Slack's
## Notes
- Was unable to change the "unknown" problem mentioned in the ticket. The API does not accept `new Error('xxx')`, even though that's being mentioned by many in the forums. It might be due to the version of Sentry that we are using.
- To search for tus issues, go to "Issues" and query `message:tus*`. Results are collapsed per event, so click on the item of interest, then click "Events" at the upper right to see all occurrences of the same problem.
