Hello, I tried to make a multipart request with an

Upload

form control but when I want to get my file from my form, It always return null on

upload

field even if I used your sample on your doc: Client side file handling

val pictureForm = formPanel<Request> {
    add(Request::upload,
        Upload(multiple = false, label = "Upload files (images only)").apply {
            showUpload = false
            showCancel = false
            explorerTheme = true
            dropZoneEnabled = true
            allowedFileTypes = setOf("image")
        })
}
button("Submit").onClick {
    GlobalScope.launch {
        val fdata = pictureForm.getDataWithFileContent()
        val firstImage = fdata.upload?.firstOrNull()?.content
        if (firstImage != null) {
            Alert.show("Image", "<img src=\"$firstImage\">", rich = true)
        }
        console.log(firstImage)
    }
}

You need to set

uploadUrl

parameter

Ahh sorry I bad, I didn't see your note 😶 Thank you !

I've added the note just now.
