Angular 0 Unknown Error Error IsTrusted True can be caused by a number of things, but the most common cause is a CORS issue. CORS (Cross-Origin Resource Sharing) is a mechanism that allows restricted resources (e.g., fonts, scripts, images, stylesheets, etc.) on a web page to be requested from another domain outside the domain from which the first resource was served.
To fix this error, you need to make sure that your server is configured to allow CORS requests. There are a number of ways to do this, depending on the server you are using.
Here are some general tips for fixing CORS issues:
- Make sure that the Access-Control-Allow-Origin header is set to allow requests from your Angular application’s domain.
- Make sure that the Access-Control-Allow-Methods header is set to allow the methods that your Angular application is using (e.g., GET, POST, PUT, DELETE).
- Make sure that the Access-Control-Allow-Headers header is set to allow the headers that your Angular application is sending (e.g., Authorization, Content-Type).
If you are still having trouble fixing the error, you can try the following:
- Use a proxy server to make requests to your server.
- Set the
withCredentialsproperty totruewhen making requests to your server. - Set the
crossDomainproperty totruewhen making requests to your server.
If you are still having trouble fixing the error, please provide more information about your Angular application and your server configuration, and I will try my best to help you.
