MobileNet library for React native throws error 'fetch undefined' - react-native

I am trying to use the mobile net library to use the trained model in my Tensorflow React Native project. However, I am stuck at a very mysterious problem. When I am trying to load the model, it throws the following error.
Cannot read property 'fetch' of undefined
I am perplexed by this error, as it seems there's no solution anywhere on the internet , even by the creators themselves. Help!

How to find which React Native module is causing a crash

I have a React Native app. It works well most of the time, but in our automated error detection framework, I can see some users infrequently run into a crash in React Native. There is a SIGABRT and a bunch of lines like this in the stack trace:
facebook::react::JSIExecutor::defaultTimeoutInvoker
I'm reasonably confident that the issue isn't directly in my application's code -- not only is the stacktrace all React Native stuff, but one of my coworkers triggered the error right after logging in a couple times, and I've never triggered this error myself despite testing the login flow many times.
Other websites make it seem like the error might actually be in a native module (but not React Native itself), but I wasn't able to figure out how to debug which native module it could be (the error doesn't happen often enough to easily just try disabling native modules one by one or anything like that).
Is there a way to get more information about what is actually causing a crash when the crash is in native code?
Thanks!

How to resolve Undefined is not an object (evaluating 'RCTToastAndroid.TOAST')

I want to run a react-native app. Before, it runs normally. An then when I add a sound and I run it again it show Undefined is not an object (evaluating 'RCTToastAndroid.SHORT')
I already open another stackoverflow question like this but it not resolve my problem
Looking at the error, even without any code from you, I have some assumptions.
You are probably trying to implement Android Toast in your app.
In the react-native docs there is an example of how to do it here and you are getting an error because of it.
Please Provide the full code where you are implementing it so we can get an proper solution.
By what you posted in your answer, there is some error in implementing Android's Toast.
OR
You have the Toast module implemented correctly, but your are in an IOS device and in you can't use Android's Toast in IOS.
If this is your case, you can try implementing something different to display and use react native Plataform.select to render the Toast in Android and something else in IOS.
