Hi @Dharani Dharan D 

Short version: this is a known limitation, not a problem with your JSON.

For the importer to attribute history to a real user, that user has to be defined
in the top-level "users" array and the history "author" must match its "name"
exactly — on Cloud that's the accountId. The official format example shows it:
https://support.atlassian.com/jira-cloud-administration/docs/import-data-from-json/

But on Cloud, account IDs in the history author are a documented bug — they come
through as anonymous/unknown even when set up correctly. It's tracked (still open)
here: https://jira.atlassian.com/browse/MIG-376

So make sure the user is defined in the "users" array first — that clears the
plain missing-definition cases. If it still shows anonymous after that, you're
hitting MIG-376 rather than a config error, so it's worth voting and watching it
for updates.
