Cannot complete end role auth after interaction event

[iFergal]

Version

Latest main on KERIA + Signify-TS [KERIA: 6ad36d5e171c599b078624c9ed4cd1c54e3c1b4a / Almost latest: 1e451d1c91e6f50edb57e2f4f41ca8b55755dac4 ]

Environment

M3, Python 3.12.2

Expected behavior

KERIA should use the correct keys to verify the end role auth from Signify, even if it has interaction events.

It should verify against the latest establishment event, but it thinks the interaction event is an establishment event and cannot find the keys to verify against. (See error below)

Actual behavior

Error in test:

HTTP POST /identifiers/testIdentifier/endroles - 400 Bad Request - {"title": "400 Bad Request", "description": "unable to verify end role reply message"}

If I print the error here in KERIA: https://github.com/WebOfTrust/keria/blob/main/src/keria/app/aiding.py#L1338-L1339 I receive:

Invalid reply from signer=EL4N4rNTl-rypDF7vccti8iIrRi90YkqyG0Hu84ca5ad, no keys at signer's est. event sn=1.
