Have you found any workaround for this? I'm running into the same issue.
No, I haven't. I am still waiting for getting this issue fixed.
Hi, thanks for filing this issue! We are unable to promise any timeline for this, but if others also have this issue, adding a +1 on this issue can help us prioritize adding this to the roadmap.
(Googler-only internal tracking bug: b/222165794)
Being able to run integration tests against features that require strong consistency is a must-have. Without this the emulator is just a key-value store and the most important feature of Firestore cannot be tested. I might as well just use Redis.
When can you get this fixed?
