Hi any update related to this issue?
I have the same issue in my app. I use stomp protocol to communicate with other devices and stomp require null character in the end of message, but I can't send this and whole communication breaks.

[kelset]

no updates on my side, sorry 😓

can anyone test a repro with the latest 0.60 RC?

I just tested this on an iOS Simulator running iOS 13, and React Native version 0.60.5 and this is still happening.

Some update on this? I can't see any linked commit ... so probably unchanged, hm? Maybe someone could remove the stale-label again?

It seems this bug was reported almost 3 years ago #12731. To me it looks like an issue that needs to be immediately addressed? I don't get why it is not a priority.

Can some moderator please mark this as "do not close", so that ugly stale-bot does not just cover a not-fixed bug?!?

AFAIK this bug is still present and such NULL-bugs are wild to find.
