To Reproduce
Steps to reproduce the behavior:

  1. Create a docker user-defined network
docker network create waltid
  1. Start instance 1 of the Issuer API
docker run --rm --name issuer1 --net waltid -p 7002:7002 waltid/issuer-api -- --webPort=7002 --baseUrl=http://caddy:9092
  1. Start instance 2 of the Issuer API
docker run --rm --name issuer2 --net waltid -p 8002:8002 waltid/issuer-api -- --webPort=8002 --baseUrl=http://caddy:9092
  1. Start Caddy as load balancer
docker run --rm --net waltid --name caddy -p 9092:9092 -v $(pwd)/waltid-services/waltid-issuer-api/distributed-test.Caddyfile:/etc/caddy/Caddyfile caddy
  1. Start Redis as data store for shared session
docker run --rm --net waltid --name redis-stack-server -p 6379:6379 redis/redis-stack-server:latest
  1. Start the Wallet API
docker run --rm --name wallet --net waltid -p 7001:7001 -it -v $(pwd)/waltid-services/waltid-wallet-api/config:/waltid-wallet-api/config -v $(pwd)/waltid-services/waltid-wallet-api/data:/waltid-wallet-api/data -t waltid/wallet-api
  1. Open http://localhost:9092/swagger/index.html
  2. Start an OIDC exchange session /openid4vc/jwt/issue
  3. Save the Offer URL
  4. Open http://localhost:7001/swagger/index.html
  5. Create a new user with /wallet-api/auth/create
  6. Sign in with the user just created with /wallet-api/auth/login
  7. Get user's wallet id with /wallet-api/wallet/accounts/wallets
  8. Claim the offered VC with /wallet-api/wallet/{wallet}/exchange/useOfferRequest

Expected behavior

Receive the offered VC.
