Summary of the issue you are facing:
When accessing a public URL of a poll I see in the logs, that the Poll app tries to resolve the GUID of the poll as a user in LDAP.
Steps to replicate it (hint: details matter!):
- install NC and configure LDAP as a user source
- create a public poll
- access the URL and monitor the nextcloud.log
