Nominatim-docker: Access to XMLHttpRequest at 'http://...' from origin 'http://...' has been blocked by CORS policy:

When I try to access the API from my app I get these errors:

Access to XMLHttpRequest at 'http://localhost:8081/search?q=Monaco&limit=5&format=json&addressdetails=1' from origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

GET http://localhost:8081/search?q=Monaco&limit=5&format=json&addressdetails=1 net::ERR_FAILED 406                             
control-geodecoder.js:161 

Can CORS this be configured when running the container?

CORS is enabled by default: #334

I saw that but I don't know how he resolved the issue

Turns out that was an issue between what the request was expecting application/json and what the server send as response text/html

In control-geodecodre.js I made the following change:

xmlHttp.open('GET', url + getParamString(params), true);
xmlHttp.responseType = 'json';
/*xmlHttp.setRequestHeader('Accept', 'application/json');*/
xmlHttp.setRequestHeader('Accept', 'text/html');
