What happened?

I installed FAIRDataPoint

git clone https://github.com/FAIRDataTeam/FAIRDataPoint.git
mvn spring-boot:run -Dspring-boot.run.profiles=development

and FAIRDataPoint-client

git clone https://github.com/FAIRDataTeam/FAIRDataPoint-client.git
npm install
# create the public/config.js as shown in the docs
npm run serve

which shows:

DONE  Compiled successfully in 14751ms                                                                                                                                           11:46:07 AM
App running at:
- Local:   http://my_hostname:8081/
- Network: http://my_hostname:8081/

When I browse (FF, Chrome) to http://my_hostname:8081/, I get the landing page; selecting the login link and entering a default user credentials as mentioned in the documentations, I get "Login failed".
The users are in the postgresql DB and I can also retrieve a token through the API for the users at http://localhost:8080/tokens .

Looking at the browser's console log:

XHR OPTIONS
http://localhost:8080/tokens
CORS Missing Allow Origin
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8080/tokens. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 403.

Is this intended?
Please let me know if I am missing something?

TIA

Hm... No reaction for 3 months. Is this project discontinued? Could an author please give a quick comment on this question? I am trying to figure out if I should be patient longer or abandon this (in principal) great tool. Thanks.
