The removal of the name attribute seems to be causing jql to now fail using plugin 3.0.12
I can see the following line here which looks to be trying to still get it. Looks like the plugin needs to use a later version of the rest client. It currently uses 5.0.4 but the latest available is 5.1.6
https://docs.atlassian.com/jira-rest-java-client-parent/5.0.4/xref/com/atlassian/jira/rest/client/internal/json/JsonParseUtil.html#L192
Line causing issue
final String username = json.getString("name");

SOAP API is deprecated as of 4/14/2019: https://blog.developer.atlassian.com/app-opt-in-api-migration/
This has caused the Confluence Publisher plugin to begin failing, not sure what other plugins are broken at this time. Issue was identified by Atlassian support under issue PSCLOUD-23492.
