[lenkan]

See reproduction script here: WebOfTrust/signify-ts#136

Steps to reproduce

In keria repository, checkout development branch, install dependencies, then run

keria start

In signify-ts repository, checkout branch of PR WebOfTrust/signify-ts#136, then run, install dependencies, and build project according to README. Then run

npx ts-node --esm examples/integration-scripts/resolve-invalid-oobi.ts

Expected result

Script logs an HTTP 4xx error, or perhaps even a HTTP 500 error. Can also be a HTTP 200, but with a failed operation.

Actual result

Script logs SocketError: other side closed and keria process crashed with

Similar thing is now happening if the oobi url contains unicode characters. KERIA process crashes. For example when copying an URL from slack by selecting text instead of "Copy address"

Tested with new images. Seems to be OK now. Closing this issue.
