Connector error at representation subscription

I have deployed two Dataspace Connectors version 7.0.1 and I am testing the subscription process between them (checking artifact, offer and representation subscription). I reach an error at Dataspace connector when trying to subscribe to the representation. This is the Swagger UI call performed.

curl -X 'POST' \
  'https://localhost:7081/api/ids/subscribe?recipient=https%3A%2F%2Fconnectora%3A7080%2Fapi%2Fids%2Fdata' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "title": "IDS Example",
  "description": "Notify on update",
  "target": "https://localhost:7080/api/representations/7a1fb097-9893-408b-8729-3d1985db5f98",
  "location": "https://localhost:7081/api/ids/data",
  "subscriber": "https://localhost:7081",
  "pushData": true
}'

These are the logs obtained from connector B (port 7081):

I have done the same for offer and artifact subscriptions and in that cases I had no error.

With the unsubscribe I am having the same error with the representation subscription/unsubscription POST /api/ids/subscribe POST /api/ids/unsubscribe
