Config:

  Sentry.config('https://[email protected]/TEAM_ID_HERE').install();

I have following issue:

I'm receiving a bunch of errors in sentry that seem to point to node_modules/react-native-sentry/lib/NativeClient.js. Specifically, the error is:

SyntaxError
JSON Parse error: Expected '}'
node_modules/react-native-sentry/lib/NativeClient.js in apply at line 63:40
    RNSentry.startWithDsnString(this._dsn);
    if (this.options.deactivateStacktraceMerging === false) {
      this._activateStacktraceMerging();
      const eventEmitter = new NativeEventEmitter(RNSentryEventEmitter);
      eventEmitter.addListener(RNSentryEventEmitter.MODULE_TABLE, moduleTable => {
        this._updateIgnoredModules(JSON.parse(moduleTable.payload)); // THIS IS LINE 63
      });
    }
    RNSentry.setLogLevel(options.logLevel);
  }

There's also a similar native error that references the module table, so they may be related:

EXC_BAD_ACCESS

Steps to reproduce:

I haven't been able to reproduce this issue. I'm just seeing a lot of Sentry events. It says the error is fatal, but I haven't heard from users that they've been experiencing any issues. It seems to be occurring on a variety of iOS versions.

Thanks for any assistance you are able to provide!

I have seen this crash 3 times now. First 2 times before update to 0.23.2, and the last one when my iPhone was attached to Xcode 9 with CPU instrument on. Xcode logs up to app crashing:

libc++abi.dylib: terminating with uncaught exception of type NSException

Sentry in the mean time recorded this crash report, screenshots attached:

I filed bug report with CodePush before with a prior crash, thinking that was the cause, but given the 14s gap here between the xhr CodePush download and the crash (gaps of minutes with my previous 2 crashes), I don't think CodePush's JSON is the cause.

Since Sentry is made to debug crashes, it being the cause of app crashes would be somewhat ironic. 🙄

esauter5 · 2017-09-25T21:41:45Z

I also use Code Push. I'll double check the stack trace to see if anything shows up there.

HazAT · 2017-09-26T07:58:51Z

Hey, this bug should have been fixed with version > 0.24.0.
Please upgrade and see if it still occurs.

Fixes #241

fungilation · 2017-09-26T09:33:33Z

My mistake, I'm already on [email protected]. I assumed 0.23.x based on releases logs here. My crash I showed above occurred on 0.24.1.

Committed fix looks good.

HazAT · 2017-09-26T09:36:11Z

@fungilation I've also added a try catch just in case.
#243

Still, it doesn't really make sense to me since I am checking for a valid JSON in Objective-C already before sending it over the bridge.

I will merge this as soon the tests pass.

fungilation · 2017-09-26T09:40:39Z

Ya. Wish sentry records what the actual JSON is in my crash report? But obviously avoiding crashing apps is the priority and the try catch is needed, though fixing JSON at the source would be better.

Fixes #241

HazAT · 2017-09-26T12:00:21Z

@fungilation Please upgrade to 0.24.2 and see if the error is gone

esauter5 · 2017-09-26T12:59:34Z

Thanks @HazAT. I will do the same and get back to you
