Why posting the request directly returns a invalid argument error but saving the request to the filesystem first and then posting it doesn't?

im trying to post a file from an API request but it returns an "ERR_INVALID_ARG_TYPE" message. my implementation is like

const file= req.files.image

cloudinary.v2.uploader.upload(

file,

{exif: true, public_id: `images/${file.name}${id}`},

function(err, response){

if(err) res.send(err)

res.status(200).json({

message: response,

id: `${file.name}${id}`

})

});

but when I save the image from the request to the file system first, it works

const file= req.files.image

const uploadPath= `${__dirname}/../uploads/${file.name}`

file.mv(uploadPath, function(err){

if (err){

return res.status(500).send(err)

}

})

cloudinary.v2.uploader.upload(

uploadPath,

{exif: true, public_id: `images/${file.name}${id}`},

function(err, response){

if(err) res.send(err)

res.status(200).json({

message: response,

id: `${file.name}${id}`

})

fs.unlinkSync(uploadPath)

});

I hope someone could help me

Thank You

Hi Duta,

Thank you for reaching out.

In your first code snippet you are not extracting the temporary file path so try again with this:

const file= req.files.image.path

When you just request `req.files.image`, you get the json response with the details of the file and uploading that results in `ERR_INVALID_ARG_TYPE`.

Please let me know if you have any other questions or queries.

Kind Regards,
Thomas
