I have the same issue and pretty much the same development env. Anybody know of solutions?

I also get this issue, both on my android TV (8.0) and emulator. It occurs when it tries to fetch(). The error is identical as those above, and repeats multiple times in a row. The fetch promise is never rejected, and the error is only visible when watching logcat. It also appears that each time I restart the app, the number of times the error appears multiplies.

It seems that my issue was solved by fixing an instance of a chained ".then(SomeClass.callback)" from the fetch request, where the callback method was not a static member of SomeClass. No JS errors or warnings appeared for me telling me that callback didn't exist on the class (it did exist as a static member of the enclosing class, however). Once I tracked this mistake down, I no longer get the exception above. The runtime exception may have been triggered by the promise chain being invalid due to this mistake, but then I'm not sure why a more relevant error wasn't tripped in js linting or even at runtime, and ended up triggering a lower level exception instead.

I'm having the same problem when setting up a project on a new RN 0.63 base:

For me it still persists, I have Xiaomi Redmi Note 7, and my code was working perfectly 1 week ago, and suddenly started giving this error... this is driving me crazy. My project needs to access Firebase Realtime Database, which is when the error happens.
The gradle probably updated something in the build, because I forced myself to create a new project yesterday, with the command
npx react-native init AwesomeTSProject --template react-native-template-typescript.
Installed clean copy of
"@react-native-firebase/app": "^8.3.1",
"@react-native-firebase/auth": "^8.3.3",
"@react-native-firebase/database": "^7.4.2",

Until then everything working, I executed the query of the firebase database (database ().ref('test'). once(...)), I managed to get the information normally (YESTERDAY),
But today I went to test again, and this error appeared in the clean project, suddenly...

The application does not display any feedback (probably because of the Unhandled SoftException), no warning. and your promise is never resolved or rejected.

I tried to synchronize the time, disable automatic time, etc.,

My react version.

I thinks this is related to the Metro Server when you hit "R" key to reload, they don't handle the connection lost for that second. (I may be talking shit.)

[workpebojot]

have the same issue, I solved mine by opening my code editor manually instead of opening my app in the terminal. For example, when I do open my code editor in git bash using code . to open VS Code. And then inside VS Code terminal I typed start cmd to open cmd terminal again. And then again I typed react-native start in the CMD terminal to start my server.

However, there's a pattern, git bash ---> VS Code ---> CMD

So I do a little experiment to prove my assumption that this kind of pattern, inherited the backend services of the parent or root I do no which one (I'm no expert but), I suspect that git bash or VS Code is affecting my react native server.

So I did open VS Code or my Code editor manually, and open my React Native project manually using Open Folder option instead of opening it in the terminal. And then I separate my terminal to VS Code and run react-native start and it worked. However, these are my own problem domain, it may not work for you
