bmunkholm commented 5 years ago

@NaveenJayaram94 You upgraded from which OS to which OS?

ithustle commented 5 years ago

Actually, I've downgraded to 2.16.0. I did it yesterday. I was suffering about last 2 weeks because of this. I'm working on two differents machines. Win and MacOS. (10 and High Sierra)

NJJ2 commented 5 years ago

I downgraded from Ubuntu 18.10 to 17.10. Yesterday in 18.10 its working fine, today downgraded my os, in first compile only its throwing this error. I don't know what to do

jgplane commented 5 years ago

Happening to me too. I haven't updated my OS or realm version. Not sure this is related, but the error started popping up after I ran these commands:

rm -rf node_modules
npm cache clean
npm install
NJJ2 commented 5 years ago

but its work well without debugging, but without chrome debugging its very difficult develop RN App. Searching for other mobile NoSql DB.

bmunkholm commented 5 years ago

@NaveenJayaram94 Have you tried to use Safari on Mac? Others have great experience with that instead of Chrome.

NJJ2 commented 5 years ago

@bmunkholm , I use Ubuntu 17.10. so only option left is the firefox browser. Tomorrow I'll test it and update here. thanks

wesleyguirra commented 5 years ago

Some fix for this?

mistikk commented 5 years ago

It is related from last version of realm(v2.18.0). You should downgrade to 2.16.0. And dont forgot to check version number on package.json. It should be "realm": "2.16.0" not "realm": "ˆ2.16.0". I lost 1 day for that :triumph:

After that, run this code for reset all packages; watchman watch-del-all && rm -rf $TMPDIR/react-native-packager-cache-* && rm -rf $TMPDIR/metro-bundler-cache-* && rm -rf node_modules/ && yarn cache clean && yarn install && yarn start -- --reset-cache

NJJ2 commented 5 years ago

@mistikk Thanks budy. You saved me from disaster it worked after downgrading my node from 10.X.X to 9.8.0

JackHull commented 5 years ago

+1 on react-native for 2.18.0

sinhpn92 commented 5 years ago

I have same issue in v2.18.0. Downgrade to v2.17.0 is solve.

JackHull commented 5 years ago

Got it fixed by upgrading to 2.19.0-rc.4.

Jefferson-Henrique commented 5 years ago

I've commented out the line 80 from "node_modules\realm\lib\browser\index.js".

[80] //config = this._constructor(config);
[81] let schemas = typeof config == 'object' && config.schema;
[82] let constructors = schemas ? {} : null;

It had a very slow start (when debug is on) but it worked fine for me on v2.19.0.

alexmbp commented 5 years ago

+1 for 2.19.0. Working ok on 2.17.0

achilles-kosun commented 5 years ago

still there on 2.19.1 :(

realm-probot[bot] commented 5 years ago

Hey - looks like you forgot to add a T:* label - could you please add one?

alexmbp commented 5 years ago

@achilles-kosun, it’s fixed in 2.20, but there is one more issue with debug mode , that already fixed on master branch

achilles-kosun commented 5 years ago

@alexmbp That's wonderful!

Realm JS SDK Version: 2.20.1 React Native: 0.57.7 Client OS: Android / iOS Which debugger for React Native: React Native Debugger / Chrome

alexmbp commented 5 years ago

@radeno I've created a patch for myself

You can use it. It require patch-package installed and used. You will need to remove this .txt extension.

realm+2.20.0.patch.txt

radeno commented 5 years ago

@alexmbp your patch adding something is already available in 2.20.1 and as i have written what i use that version :) https://github.com/realm/realm-js/blob/cfb54f07fc7530530fc7d4e285d531d157489c33/lib/browser/index.js#L136 So there must be another issue.

alexmbp commented 5 years ago

@radeno Than it should work already. I've hardcoded version to 2.20.0

radeno commented 5 years ago

@alexmbp trust me, it doesn't. Anyway my issue is connected with https://github.com/realm/realm-js/issues/2128 and will be fixed for real with this PR https://github.com/realm/realm-js/pull/2157

cmelchior commented 5 years ago

I tested with a completely new project using RealmJS 2.21.1 and debugging seems to work fine there. Closing.
