No public key could be resolved for alice

[stefanlack]

Current Behavior

When I try to request the catalog from bob as user alice, I do not get expected result.

curl --request POST \
  --url {{URL_EDC_ALICE}}/management/v3/catalog/request \
  --header 'content-type: application/json' \
  --header 'user-agent: vscode-restclient' \
  --header 'x-api-key: password' \
  --data '{"@context": {"@vocab": "https://w3id.org/edc/v0.0.1/ns/","odrl": "http://www.w3.org/ns/odrl/2/"},"@type": "CatalogRequest","counterPartyAddress": "{{URL_EDC_BOB}}/api/public/v1/dsp","counterPartyId": "BPNL000000000002","protocol": "dataspace-protocol-http","querySpec": {"offset": 0,"limit": 50}}'

I get
[{"message":"{\"errors\":[\"No public key could be resolved for key-ID 'did:web:alice-ih%3A7083:alice#signing-key-1'\"]}","type":"BadGateway","path":null,"invalidValue":null}]

Expected Behavior

Catalog Data is returned

Steps To Reproduce

• Install mxd
• Follow tutorial on https://github.com/eclipse-tractusx/tractus-x-umbrella/blob/main/docs/user/guides/data-exchange/provide-data.md

We have to investigate and find out where the key should be added, so that that step can be executed. Can someone please give us a hint?
