Bug: Multiple CORS header 'Access-Control-Allow-Origin'

[alexgarel]

I run the docker version of beehive:

docker run --rm -p 8181:8181 fribbledom/beehive

I open http://127.0.0.1:8181/ if firefox.

I get this error in console:
Multiple CORS header 'Access-Control-Allow-Origin' not allowed

The page remains blank.
The preflight CORS request (OPTION), do return multiple 'Access-Control-Allow-Origin' headers:

HTTP/1.1 200 OK
Access-Control-Allow-Headers: authorization, content-type
Access-Control-Allow-Headers: content-type
Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE
Access-Control-Allow-Methods: GET,GET
Access-Control-Allow-Origin: *
Access-Control-Allow-Origin: http://127.0.0.1:8181
Allow: GET,GET

In docker console, everything seems ok.
