Credential information could not be extracted / Couldn't receive credential from OpenID4VCI offer

[jack-robson]

I don't think the app is working as you expect.

Steps to reproduce:

1. Run latest version in Expo (or use Play Store app)
2. Scan in this QR

This produces the "Credential information could not be extracted" error inside the app.

Note, the QR seems valid as I've managed to scan it into a different wallet app. And I got it from https://launchpad.mattrlabs.com/.

I've also tried many QRs, all produce the same error.

Looking at the expo logs, it says

Could you try running it from #71?

This should support the latest version of MATTR Launchpad (with Jwt format). We'll merge this soon when some underlying dependencies are updated
