This problem is related to default Webkit security settings which forbid doing Ajax requests on the local filesystem. You have at least two possible solutions:
- Serve index.html with some web-server like Nginx or Apache. This will emulate remote website and thus trick your browser. With Allure CLI 2.0+ this can be done using the following command:
$ allure report open
- Use –allow-file-access-from-files Chrome flag. See details in this question.
