Problem issue credentials (json-ld) using did:sov: as issuer and subject
I'm having a problem with the issue credentials (json-ld) between Alice and Faber
Faber "connection id": "8daa5789-487d-46cc-986a-cd7a2729a524" "did": "D3dJPj916xW2hkr5bwdkVx" (public and posted) "verkey": "7ZmwZTvLeCP5RZw6BASqY8kd3G7cQQYfPbdpyLC2n8Pg"
Alice "connection id": "c5d9affa-6e4d-45e0-b1ad-04d8c5b442f7" "did": "21gMuZprYu7FCWRp12C3a2" (public and posted) "verkey": "Yyww8YhX1CVLYGL7teqPEy6ERjxMnTqic4mcbtD3zSf"
Flow:
Faber send a credential to Alice (using the sov did of alice as subject)
curl -X 'POST' \
'http://0.0.0.0:8021/issue-credential-2.0/send' -H 'accept: application/json' -H 'Content-Type: application/json' \

Alice get the credential and store it using id 123456789, then i run
curl -X 'GET' 'http://0.0.0.0:8031/credential/w3c/123456789' ....
and get the following:

Why credentialSubject.id has been changed? did:key:zUC76cs belong to Alice but it is bls12381g2 key, wallet_only and not sov did that i can use later for send presentations ?
I am not able to replicate the problem, it is working correctly on my end.
I tried with bls12381g2 key [wallet_only] and without in wallet. Also tried with a different posted DID for Alice [holder].

@shaangill025 Thanks for your reply but what do you mean exactly with "I tried with bls12381g2 key"? When i generate the did for alice, i'm using "key_type": "ed25519" because i want a sov did. and then using that did as holder and the already generated did for faber as issuer.
Could the connection be the problem? What I'm doing is:
I'm starting Faber and Alice Demo like the following:
LEDGER_URL=http://dev.greenlight.bcovrin.vonx.io ./run_demo faber --events --no-auto --bg LEDGER_URL=http://dev.greenlight.bcovrin.vonx.io ./run_demo alice --events --no-auto --bg
Using Faber.agent: I call Get wallet/did and get the did (it has only 1 at the start) and this did is used as isser
Using Alice.agent: I create a local DID ("key_type": "ed25519" ), register it manually on http://dev.greenlight.bcovrin.vonx.io
and assign it to public using Post wallet/did/public and this did is used as holder
Using Faber.agent i create out-of-band invitation (auto_accept: true, use_public_did: true and handshake_protocols: https://didcomm.org/didexchange/1.0)
Using Alice.agent i receive the invitation (auto_accept=true)

Any updates to this? @shaangill025 -- perhaps you could add this to your list to retry?
This sounds like the holder DID override behavior that I corrected in #2341. Now, if the credential offer from the issuer contains a credentialSubject.id, as is the case in your example, the holder will NOT override the subject with a DID key. This was originally done to help ensure that the holder could later present a proof of possession for the credential subject ID.
