Https cors false on Confluence DataCenter Plugin Development instance

[Vikash Kumar]

I am using GitHub codespaces to run Confluence plugin. I am able to run the plugin in Codespace but it's giving me https URL and because of that I am see errros in the log such as: 403 Forbidden / allowed via CORS: false

Similar to one mentioned here:

- https://community.atlassian.com/t5/Crowd-questions/Error-in-log-credentials-in-request-true-allowed-via-CORS-false/qaq-p/1089705

When I am trying to disable https and make it http, Codespace is not allowing to do that. So what options do I have to fix this 403 / allowed via CORS: false error ?

Thank you!
