Failed after press "Approve" button, app crash unexpectedly or throws "Error generating proof"

Platform: MacBook Pro(m1 pro)

Os version: macOS Ventura 13.2.1

Question description: After following the instructions list in README.md, I almost finished all but failed at the last step, after press "Approve" button in app, except crash unexpectedly, always got an "Error generating proof" page as below:

The config in run.sh list below:

ONCHAIN_ISSUER_DID=did:polygonid:polygon:mumbai:2qCU58EJgrEMFbapsV5V79MpbFjFwrYsYas9f6bma1

ONCHAIN_ISSUER_CONTRACT_ADDRESS=0xbC0F0743347a5Eb4ddb6805cf87d7e0dfeABF21d

And the contracts deployment output are list below:

I also have tried switching circuit id to Credential Atomic Query MTP On Chain but got the same error.

So what should I do for generating the proof correctly?

[ilya-korotya]

Hi @kervinct. Could you please, share the proof request you used for generation proof, please? You can copy the request JSON from the browser console.

[ilya-korotya]

Ohhh. I see why you have the error. Your on-chain issuer contract was deployed with the state contract set to 0xd6CC01505FEf88fDAcb06a1fB1E9E3FdB88AcBA1. I think you should deploy the on-chain issuer contract separately from the state contract and pass the initialized on-chain issuer contract the correct state contract address.

Thanks for your reply, I will try that and report the result as soon as possible.

[kervinct]

@ilya-korotya Yeah, your are right, now I can correctly generate the proof, thanks for your help!
