Got the same error with 0.58.0-rc.1

[dluksza]

Version 0.8.2 still doesn't work with react 0.58

[jhwheeler]

We have the same issue with latest version of Expo. Moreover, the app won't open with the remote debugger enabled. It works perfectly fine without the remote debugger.

[stevenspiel]

Getting the same error with 0.58.0-rc.2

[Joepus]

Same error. also on just released v0.58.0. Browsers debuggers works, RNDebugger gives above error.

[rkram5424]

Getting the same error for 0.58.1

[Tim1023]

Getting the same error for 0.58.0

[gostrafx]

[pjay79]

[Alekseyideas]

The same "react-native": "0.58.1"

[phamdungtsx]

same error RN 0.58.1

[mukeshmandiwal]

same issue in 0.58

[Eugnis]

Confirm 0.58.1 same

[theharness]

Same error 0.58.1

[dmitryrn]

Same, 0.58.1

[Eugnis]

I've find out that in 0.58 delta patcher was updated so this issue appeared.
I've fixed it by myself and added PR #307 so check it out if it works for you (clone fork, npm run build && npm run start)
For me it works on Windows and Android, should work on others

[Baskerville42]

the same situation

"react": "16.6.3",
"react-native": "0.58.1",

Uncaught (in promise) TypeError: Iterator value v is not an entry object
    at new Map (native)

[rikardocorp]

It works for me on macOS Mojave, RN 0.58.1, Xcode 10 and iOS 11.2.
Bad part is that I'm unable to debug async storage when using showAsyncStorageContentInDev()
I get TypeReference error showAsyncStorageContentInDev is undefined when trying to run it.

[ithustle]

Same error

"react": "16.7.0",
"react-native": "0.58.2",
Uncaught (in promise) TypeError: Iterator value v is not an entry object
    at new Map (native)

[OriginLive]

Can you please fix this error already...

[RWOverdijk]

@OriginLive Or you fix it. It's open source software.

@glothos Could you add that comment in the PR?

@Eugnis Nice find! I'll watch the PR.

[tinuts]

@Eugnis Thanks ! You saved my day

I just downloaded the latest version of the debugger and it fixed the problem for me.

[witalobenicio]

@wmoore98 where did you get it?

[wmoore98]

I had the debugger opened and selected the menu option RND -> Check for Updates..

[wmoore98]

I had the debugger opened and selected RND->Check for Updates... from the menu.

@wmoore98 I just use the default debugger. When we choose debug js remotely.
I don't know if is this debugger you're talking about.
Could you show a print of yours?

[wmoore98]

I got the debugger from this site: jhen0409/react-native-debugger. Just click on the link under Installation to go to the release page and download the version for your machine.

[elisealcala]

I just close and reopen debugger and works.

[Johncy1997]

I am getting the same error on debugging

[Dror-Bar]

@elizalc Haha, sometimes the simplest solution is the right solution. I was debugging one app, then switched to another and got this error. Thanks ;)

[qingjiaowochengzd]

i solve the problem by download newest debugger vision

[stenmuchow]

For the lazy person like me who just wants the damn fix, to re-install react-native-debugger, run:

brew cask reinstall react-native-debugger

[MateusAndrade]

Just updated to the newer version solved this problem

[witalobenicio]

I just close and reopen debugger and works.

Thanks a lot

[pacozaa]

[raman-sidhu]
