Cannot update a record with pending changes

[KotoriMinami]

Description:

Some messages within the conversation encounter the following issues.

 Diagnostic error: Cannot update a record with pending changes

Environment Information:

• Rocket.Chat Server Version:
• Rocket.Chat App Version:
• Device Name:
• OS Version:

Steps to reproduce:

1. Enter a conversation, with a very low probability of occurrence.

Expected behavior:

Within the conversation, messages can be updated and further actions can be performed.

Actual behavior:

There's a probability that a certain batch of messages may not update correctly.

Additional context:

After examining the logs, it is suspected that the issue is caused by the following:

In the https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/bb59d980b23484a7897611de77d6847bcfad77f4/app/lib/methods/subscriptions/room.ts#L314 method that handles message updates over a certain period of time. All creations and updates are stored in https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/bb59d980b23484a7897611de77d6847bcfad77f4/app/lib/methods/subscriptions/room.ts#L244

If there is a slightly long-running task when executing https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/bb59d980b23484a7897611de77d6847bcfad77f4/app/lib/methods/subscriptions/room.ts#L332

before reaching db.batch, https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/bb59d980b23484a7897611de77d6847bcfad77f4/app/lib/methods/subscriptions/room.ts#L341 because https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/bb59d980b23484a7897611de77d6847bcfad77f4/app/lib/methods/subscriptions/room.ts#L327 the next timer execution may be triggered.

At this point, https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/bb59d980b23484a7897611de77d6847bcfad77f4/app/lib/methods/subscriptions/room.ts#L320 the creation and updates from the previous batch will be lost, causing them to not reach the db.batch method.

As a result, Model._preparedState will remain in an executing state in memory and will never recover. Consequently, this batch of messages will not receive any updates.
