Я новичок в Spring Boot, и при написании API загрузки файлов я получаю следующую ошибку:

## MULTIPART (MultipartProperties)
# Enable multipart uploads
spring.servlet.multipart.enabled=true
# Threshold after which files are written to disk.
spring.servlet.multipart.file-size-threshold=2KB
# Max file size.
spring.servlet.multipart.max-file-size=200MB
# Max Request Size
spring.servlet.multipart.max-request-size=215MB

## File Storage Properties
# All files uploaded through the REST API will be stored in this directory
file.upload-dir=C:/Projects/SpringBootProject/Primesolutions/PrimeSolutions/FileUpload

Я пытаюсь прочитать свойство загрузки файла и передать его классу контроллера.
