The log always reaches this at the end when trying to update:

AttributeError: 'EventAttachment' object has no attribute 'update'

Guessing is this is due to the fact we had this(SENTRY_FEATURES[‘organizations:event-attachments’] = True) on during the original setup of Sentry v10.0.0.dev something rather version and now it has a problem with it when we try to get to the latest stuff.

Do believe we got the latest sentry.conf.py from git for the update and we put that line in the new sentry.conf.py but not sure what else to try to get past this issue. Ideas?

Thank you in advance!

I’m not fully sure why this migration no longer works, my guess is due to a Django upgrade after it was originally written.

In any case, this migration is not super critical. Without it, old event attachments will not show up on the Issue Details > Attachments tab. You can just skip it and then continue the upgrade:

sentry django migrate --fake sentry 0020
sentry upgrade

The above commands will become the following in your case (since you are using our on-premise repo):

docker-compose run --rm web django migrate --fake sentry 0020

You can then run ./install.sh again to continue with the rest. I’ll still be investigating the root cause.

Submitted a potential fix here @SuperServer: https://github.com/getsentry/sentry/pull/17755. Feel free to follow that and giving it a try instead of skipping over this migration.

Awesome to wake up to see a fix! I’d give it a try but I’m not exactly sure how I would try/implement said fix. Quick hints on where to go/change? Thanks!
