Error at startup of server - Error: missing key for signatory 0

[MrMuffin0]

Hi,

I'm trying to set up a Keyrock instance at the moment using the newest release 8.4.0 on Ubuntu. When I try to start the server after following the installation steps in the documentation the web GUI is reachable and I can interact with it but the following error is thrown:

(node:1733) UnhandledPromiseRejectionWarning: Error: missing key for signatory 0 at /opt/fiware-idm/node_modules/node-jose/lib/jws/sign.js:294:26 at Array.map () at Object.createSign (/opt/fiware-idm/node_modules/node-jose/lib/jws/sign.js:272:23) at Object.create_jwt (/opt/fiware-idm/controllers/extparticipant/utils.js:283:25) at processTicksAndRejections (internal/process/task_queues.js:97:5) at async retrieve_participant_registry_token (/opt/fiware-idm/controllers/extparticipant/utils.js:111:10) at async fetch_access_token (/opt/fiware-idm/controllers/extparticipant/utils.js:309:19) at async inner_get_access_token (/opt/fiware-idm/controllers/extparticipant/utils.js:347:14) at async fetch_trusted_list (/opt/fiware-idm/controllers/extparticipant/utils.js:359:26) (node:1733) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api cli.html#cli_unhandled_rejections_mode). (rejection id: 2) (node:1733) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

The following versions are installed:

Ubuntu: 22.04 Nodejs: v18.19.1 Npm: 10.2.4

Could you help me solve this error?

Edit to add:

The issue does not appear in Keyrock version 8.3.3.
