UnknownError: Attempt to get a record from database without an in-progress transaction

[skyqrose]

My app occasionally gets error reports from clients of UnknownError: Attempt to get a record from database without an in-progress transaction.

It's always on iPhone.

I don't have a stack trace, but it's likely happening in a call to IDB.get(key), though we also call IDB.del(key) nearby.

We're using idb-keyval version 6.2.1.

This isn't a big deal for us, cuz our app just uses IDB as a cache, so we gracefully catch the error and ignore the cache, but I thought I'd submit a bug report anyway in case it matters more to someone else.

Any news? More important for us since our app rely on heavy cache that we don't want to totally reset/ignore :)

Can anyone provide a way to reproduce this error?

We're experiencing the error as well but have had no success reproducing it.

It's one of several IndexedDB-related error reports that we only see on iOS, which makes me suspect that iOS Webkit's IndexedDB implementation simply has bugs. See https://bugs.webkit.org/show_bug.cgi?id=202705 and the "depends on" list under https://bugs.webkit.org/show_bug.cgi?id=165889.
