[2.19.2] Possible Unhandled Promise Rejection (id: 0): Error: Promise timed out

[efstathiosntonas]

I get this on app start:

Possible Unhandled Promise Rejection (id: 0):
Error: Promise timed out
Error: Promise timed out

and later on:

Promise Rejection Handled (id: 0):
 WARN    This means you can ignore any previous messages of the form "Possible Unhandled Promise Rejection" with id 0.

  export const createPromise = <T>(

• analytics-react-native version: 2.19.2
• Integrations versions (if used):
• React Native version: 0.74.2
• iOS or Android or both? Both

Steps to reproduce

Expected behavior
don't know
Actual behavior
throws promise timeout

It appears that this is happening only on 2.19.2, downgrading to 2.19.1 does not throw the rejection any more.

It may be unrelated, but I was getting the same error mentioned in the OP and also: Queue timeout before completed restoration. Downgrading to 2.19.1 resolved both of them.

hi folks thanks for the report- will prioritize this and follow up asap.

@efstathiosntonas @gitwilliam At present, the only PR I can find related to this issue is #943. From what I can tell in my investigation so far, these errors on app launch are expected and described in detail in that PR mentioned above. The change was introduced to prevent flushing before plugins (including SegmentDestination) are initialized. I can reproduce the warnings you are seeing but I am not experiencing any event loss.

Please let me know if you are experiencing event loss or any other unintended/regressive behavior and we can go from there.

@alanjcharles No event loss, but I'm getting these errors every few seconds when running my app (not just at app launch). Please have them as opt-in through a config flag or something, it's clogging up my debug terminal!

[efstathiosntonas]

@alanjcharles same as @jvgeee, It’s clogging the terminal and it’s really annoying since our minds automatically tries to find out what is going on when we see a promise rejection happening 😂

[paulina-grunwald]

I have same problems. any solutions?

[engineeringcontractorstockpile]

We also have that here.
