Refused to connect to ‘http://localhost:8100/.well-known/appspecific/com.chrome.devtools.json’ because it violates the following Content Security Policy directive: “default-src ‘none’”. Note that ‘connect-src’ was not explicitly set, so ‘default-src’ is used as a fallback.
Currently, I am studying Ionic at the university, and today, three of my students encountered a similar issue. I am uncertain about how to assist them effectively. Additionally, there was an issue with a TS module versions.
We spent quite some time investigating and found that the issue only appeared in new projects, while older ones worked fine. The temporary solution was to downgrade @ionicionic**/angular** from 8.7.4 to 8.0.0 and reinstall the npm packages.
