Allure report html is not loading json data

I run tests using Java and collect the results with Allure. As a result folder allure-results generated with banch of json files. I can see the report if I use
allure serve allure-results.
However, I want to generate html that I can view any time later. So I do it by allure generate allure-results --clean -o allure-report. As a result folder with html file is generated. However, when I open this file the data is not loaded. Please see the attachment below.
In console I get CORS policy errors. The example is below.

Acess to XMLHttpRequest at 'file:///Users/jgitlin/Documents/proj/CommServ_E2E_Automation/build/allure-results/widgets/summary.json' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, isolated-app, chrome-extension, chrome, https, chrome-untrusted.

Is there a problem in the way I generate the report or is there a way to see the html properly?

You can easily use any web server of your choice to serve the Allure report, for example Python's built-in HTTP is ok let me explain it to you

first of all open a terminal or command prompt and navigate to the directory where the Allure report is generated

then, start Python HTTP server like this (it will start the server on port 9001, but you can use any other port number you like!):

python -m http.server 9001

at the end, open your browser and go to http://localhost:9001/allure-report to view the Allure report!

with this method,you are bypassing the CORS policy and allowing the browser to load the necessary resources properly

good luck !

You can use allure commandline to see actual report;

> allure open allure-report
