what is my problem
The issue is caused by an incorrect service naming and configuration. The class is named FromService, which appears to be a typo and should be FileService. Because of this mismatch, the implemented interface name does not align with the intended file-handling responsibility, leading to Dependency Injection errors. Additionally, the upload logic does not ensure that the target directory exists before creating the file, which can cause runtime exceptions. Finally, the service may not be properly registered in the DI container, resulting in the service not being resolved at runtime.
