[2.1.0] TypeError: undefined is not a function, js engine: hermes

[Bardiamist]

I have error TypeError: undefined is not a function, js engine: hermes after update from 2.0.0 to 2.1.0. Only on Android and only if Debug is off.

Update: release apk also crash on start.

Minimum steps to reproduce:

1. react-native init (I tested on version 0.61.2 and 0.61.3 version)
2. Enable Hermes (one line change, see documentation)
3. import 'react-native-auth0';

@Bardiamist - Thanks for the report here and apologies for the trouble. Can you give us a bit more to go on here? Possibly sample code that's causing the issue or a line number where that error is coming from?

[Bardiamist]

Just error on start.

But I can see what error in jsrsasign/lib/jsrsasign.js (thanks Reactotron)

[Bardiamist]

That error occurs only if Hermes is enabled.

Minimum steps to reproduce:

1. react-native init (I tested on version 0.61.2 and 0.61.3 version)
2. Enable Hermes (one line change, see documentation)
3. import 'react-native-auth0';

I see jsrsasign dependency was added in this commit and this not works on Hemes.

Please fix it. Hermes is very good thing and will enabled by default in future.

@Bardiamist I've downgraded to 2.0.0 for hermes support.

[GuillaumeAmat]

For the record:

• react-native-auth0@2.1.0 + Hermes = ❌
• react-native-auth0@2.1.0 + Hermes + Debug mode = 👌

[export-mike]

hmmm @2.1.0 is not going to work either.

jsrsasign is a dependency

2.1.0

npm list jsrasign 
   ┬ react-native-auth0@2.1.0
  └── jsrsasign@8.0.12

2.0.0

 npm list jsrsasign
/Users/mike/projects/temp-app
└── (empty)

@Widcket can you take a look at this please

[Widcket]

Thanks everyone for the information. This issue is in our radar, and we’re currently evaluating options.

Having the same problem with 2.1.0. Only downgrading to 2.0.0 fixed it

@Bardiamist & all, I've put a PR that replaces jsrsasign. I've tested it and an Hermes enabled app works fine now. We'll be making a new release next week but in the meantime I'd love you have your feedback.

You can try the branch code by installing the package this way:

yarn add https://github.com/auth0/react-native-auth0.git#temp-idtv-2

[Bardiamist]

I checked, that works for my application.

2.0.0

 npm list jsrsasign
/Users/mike/projects/temp-app

Thanks a lot :)
We removed jsrassign in our project and crash issue is fixed.
