Credential Exchange - 'cred_def_id': ['Missing data for required field.'] - aries-agent calling create method Error: Request failed with status code 422

The issuer gets stuck while issuing credentials to the BC wallet agent. Any help on how to resolve this error is much appreciated. Thanks in advance!

I managed to resolve that error.. Think the issue was due to... switching back and forth between local mode and dev mode. I think it messed up the cred_def. After starting over from scratch I no longer see the error.

Started the service in this order:

1. Von-network
2. issuer-kit in local mode
3. BC Wallet (with metro port set to 10001 to prevent default port 8081 conflict with issuer-kit - export RCT_METRO_PORT=10001)
