`nil` crept up in exceptions

Environment

sentry version: 10.7.1

Issue

I can't quite tell what is going wrong here or what is failing because of nil. We updated to 10.7.1 to fix some of them ( #779 ), but we're still seeing these after the upgrade for this error and a couple other ones as well. If I had to take a SWAG, it's because frames is nil, due to this PR: https://github.com/getsentry/sentry-elixir/pull/775

Actually, this may be a duplicate of https://github.com/getsentry/sentry-elixir/issues/786

[savhappy]

@BobbyMcWho yep yep this is a duplicate of #786 and was fixed with PR #787

[BobbyMcWho]

Okay, thanks, is master sha safe to use, or should we wait for a release?

[savhappy]

Yes, you can try out the fix on the master branch. We'll do a release soon 💟

Hey! @savhappy I was wondering if you have a timeframe on the 10.7.2 release. I am asking because I am weighing my options between downgrading or waiting for the new release.

[savhappy]

@whatyouhide timeframe on this?

[whatyouhide]

@savhappy @tomekowal once https://github.com/getsentry/publish/issues/4371 is addressed. @savhappy you can ping Neel and Stephanie on Discord to speed things up if needed.
