irmajs's Issues
Disclosure flow on iOS sometimes results in promise rejection
I ran into this when working on nuts-foundation/irma-web-glue#2. I hope you can reproduce it on your end.
Running the irmajs browser example on iOS results in unpredictable behaviour. I see three different possible end states:
1. Rejected promise "DONE"
This happens when I kill the IRMA app and go through the disclosure flow.

2. Rejected promise with connection error
This happens most of the time when I have my IRMA app already open.

3. Resolved promise (as intended)
This happens sometimes when I have the IRMA app already open.

Statusevents unsupported by server
The irma.js library makes a call to the IRMA server on /statusevents, line 259 in index.js.
It looks like the server has not implemented this feature as we get a 501 HTTP response with the message:
{"status":501,"error":"UNSUPPORTED","description":"Unsupported by this server"}
We are using the IRMA demo server at: https://metrics.privacybydesign.foundation/irmaserver.
I'm not sure if this is an issue with the server, or that client is calling a deprecated endpoint which used to exist in older versions of the server.

[Security] dependencies are using an outdated lodash version with security issues
It would be good to updated all dependencies. It would also be good to use a tool like dependabot to automate this process.
