I previously had my endpoint set up to handle png and jpg files successfully. However, I wanted to restrict it to only allow webp files. So, I updated the file filter callback accordingly. Unfortunately, now Multer does not save any files other than png or jpg without giving an error. It returns an object indicating successful saving but nothing actually gets saved on the disk.
What could be causing this issue?
Here is the configuration object I am using (specific to the tsed framework):
const storage = multer.diskStorage({
destination: function (req: any, file: any, cb: any) {
cb(null, './uploads')
},
filename: function (req: any, file: any, cb: any) {
let extArray = file.mimetype.split("/");
let extension = extArray[extArray.length - 1];
cb(null, file.fieldname + '-' + uuidv4() + '.' +extension)
}
})
multer: {
storage: storage,
dest: `${process.cwd()}/uploads`,
limits: {
fileSize: 7340032,
},
fileFilter: (_req: any, file: any, cb: any) => {
// Previous condition checking mimetype was removed for testing purposes with different mimetypes
return cb(null, true);
}
}
My endpoint implementation:
@Post("/photo")
@Authorize("jwt") @Security("jwt")
@Returns(200)
@Returns(401)
@Returns(404)
private async simpleUpload(
@MultipartFile("file")
file: PlatformMulterFile) {
if (!file) {
throw new NotFound('file not found');
}
console.log(file);
return{filename : file.filename}
}
Despite always receiving a 200 response, the console log output shows no file being saved on the disk when attempting to upload pdf or svg files.
