Same issue here, how to fix this please?

I am also experiencing the warning of warning: the variable "XXX" was not declared in function, except the build completes successfully and the app appears to run properly, though I am concerned about what potential effects this has that I am missing.

I'm on React Native 0.61.2, and I get this warning for the following variables:

any fix? v0.62.2 still facing issue

[Eli-Nathan]

RNv0.63.2 still facing the issue. Any word on this?

[zmnv]

Hello. Still exist with 0.63.2.

[divanc]

I am also experiencing the warning of warning: the variable "XXX" was not declared in function, except the build completes successfully and the app appears to run properly, though I am concerned about what potential effects this has that I am missing.

I'm on React Native 0.61.2, and I get this warning for the following variables:

• "DebuggerInternal" was not declared in function "s 4#"
• "clearTimeout" was not declared in function "componentWillUnmount 1#"
• "setTimeout" was not declared in function "touchableHandleResponderGrant"

• "setInterval" was not declared in function "update"

What helped me was adding extraPackagerArgs inside app/build.gradle

project.ext.react = [
    extraPackagerArgs: ["--sourcemap-output", "$buildDir/intermediates/sourcemaps/react/release/index.android.bundle.packager.map"],
    enableHermes: true,
    hermesCommand: "../../node_modules/hermes-engine/%OS-BIN%/hermesc",
]

and then sync project with gradle file , ./gradlew assembleRelease.

Warnings remain, yet app is at least launching

[jefersondaniel]

I upgraded to RN 0.63.4 and I'm seeing these messages at build time, but the app is running fine.

[Villar74]

still happens in 0.64

[messenja]

Still in 0.64.0
App doesnt work properly in release mode ( doesnt work data fetching from api, mb because of "XMLHttpRequest" was not declared in function ... ? i dont know, but in debug mode its ok)

[AkashBabu]

After upgrading to 0.64.2(Hermes enabled) from 0.61.5, debug build works fine, while release build seems to be failing.
Below are the logs:
