Hey, I've had a similar problem, please make sure your request URL is HTTPS not HTTP as Android from new versions doesn't allow HTTP

Unfortunately no...Best bet is debug js remotely option, moreover fetch related errors are not accurate at all for example recently I got a network request failure, then after hrs of self debugging I fixed my form data object

Try using this one. It worked for me.

Add the codes in your main AndroidManifest.xml :

<manifest 
  xmlns:tools="http://schemas.android.com/tools">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:usesCleartextTraffic="true" tools:targetApi="28"> 
    ... 
    </application>
</manifest>

[adnanpirota]

Thanks @alexPimentel for me it works even without tools:targetAPI="28".

me too

Just had this issue and want to comment that this works
My env:
RN Version 0.60.4,
buildToolsVersion = "28.0.3"
minSdkVersion = 16
compileSdkVersion = 28
targetSdkVersion = 28
supportLibVersion = "28.0.0"

further to @alexPimentel's post:

usesCleartextTraffic

"Indicates whether the app intends to use cleartext network traffic, such as cleartext HTTP. The default value for apps that target API level 27 or lower is "true". Apps that target API level 28 or higher default to "false"."

explains why this is a "sneaky regression".

However, I am running it on lower version of API also but it is not working.

I am facing the same issue in android release apk. React native version is 61.5. Tried with android:usesCleartextTraffic="true"( tried with fetch and axios ,still not working). Also tried with http and https also, still no luck.
Everything works fine in debug mode.

@cjahfar1 Are you solve it?

[cjahfar1]

@cjahfar1 Are you solve it?

Yes,. Actually "android:usesCleartextTraffic="true"" fixed the issue. There were another error which was blocking the api calls and the error was swallowed since this error happens in saga function. Sorry for not updating here.

Status code 400 means, bad data. Double check the payload format. You are getting response 400, that means, API call is getting initiated.
