To help developers understand the issue of "Script Error" when dealing with cross-origin scripts, browsers intentionally hide errors originating from script files from different origins for security reasons. However, there are potential reasons why insight into these errors is necessary, such as serving JavaScript files from a different hostname or using libraries served from community CDNs. To get visibility into these errors, developers can add CORS attributes and headers to the scripts, which allows browsers to fetch the file without transmitting potentially user-identifying information. Alternatively, they can use try/catch blocks to wrap 3rd-party code and capture error messages and stack traces. This approach is recommended when trying to fix script errors caused by cross-origin scripts.
