If you see an error while trying to fetch a URL, it usually means the request never reached the server or the server didn't respond.
Modern web ecosystems enforce strict security perimeters. Trying to programmatically input an encoded local path like file:/// directly into standard web clients causes several system failures:
Then check:
: If the server-side backend decodes the text string before passing it to an execution command, it translates the string back into file:/// , granting the application direct access to local system resources. Real-World Impacts of Local File Vulnerabilities
// Windows path is automatically normalized const response = await fetch("file:///C:/path/to/file.txt"); const text = await response.text();
The string fetch-url-file-3A-2F-2F-2F is a hybrid, combining plain words with coded characters. Let's decode it step by step: The keyword appears to be URL-encoded

Server-side environments like Node.js can use fetch (with polyfills) or the fs module to read local files, though this must be done with extreme care.
