Calling gateway.getCloudFeedback(transferId) in Jira Cloud Migration Assistant always returns a HTTP 404

Issue Summary

When calling

gateway.getCloudFeedback(transferId);

in Jira Cloud Migration Assistant, it always returns a HTTP 404. 

This works in Confluence Cloud Migration Assistant as expected.

Steps to Reproduce

1. Implement onStartAppMigration() and call gateway.getCloudFeedback(transferId);

Expected Results

If data is available then return feedback from app migration platform.

Actual Results

HTTP 404 is always returned.

The below exception is thrown in the atlassian-jira.log file:

2021-06-24 14:00:47,036 Caesium-1-2 WARN ServiceRunner     [c.vendor.impl.MyPluginComponentImpl] getCloudFeedback error

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
