Error uploading Multipart to MongoDB using Ktor

I'm trying to upload a JPEG to MongoDB using Ktor and Kotlin but keep getting an error:
java.io.FileNotFoundException: /document/image:32: open failed: ENOENT (No such file or directory)
Please help if someone knows what I am doing wrong here
It is a strange error, because I'm sure that uri is ok. I can display an image in app with this.
First things first:
KTOR SIDE:
fun Route.uploadFile(
app: Application){
val client = KMongo.createClient()
val database = client.getDatabase(IMAGES_DATABASE_NAME)
val bucket = GridFSBuckets.create(database, "images")
post("/upload_photo") {
try {
val multipartData = call.receiveMultipart()
multipartData.forEachPart { part ->
if (part is PartData.FileItem) {
val fileName = part.originalFileName as String
withContext(Dispatchers.IO) {
bucket.uploadFromStream(fileName, part.streamProvider())
}
call.respond(
message = ApiResponse(
success = true,
message = ""
)
)
} else {
call.respond(
message = ApiResponse(
success = false,
message = ""
)
)
}
}
} catch (e: Exception) {
app.log.info("Error: ${e.message}")
call.respond(
message = ApiResponse(
message = "Error: ${e.message}",
success = false
),
status = HttpStatusCode.BadRequest
)
}
}
API INTERFACE:
#Multipart
#POST("/upload_photo")
suspend fun uploadPhoto(
#Part filePart: MultipartBody.Part
):ApiResponse
Now, I suppose that the problem occures on kotlin Android App side:
Function where the problem occures:
override suspend fun uploadFile(photo: Uri): ApiResponse {
return try {
val file = photo.path?.let { File(it) }
val requestBody = file!!.asRequestBody()
val body = MultipartBody.Part.createFormData("photo",file.name, requestBody )
Log.d("Upload", body.toString())
ktorApi.uploadPhoto(body)
} catch (e: Exception) {
Log.d("Upload: ", "{ $e.message }")
ApiResponse(
success = false,
error = e
)
}
}

I found a solution to my problem.
To make a post with Uri possible is it necessary to create a temporary file in local cashe. For example with the method like thise:
private fun createFileFromUri(name: String, uri: Uri, context: Context): File? {
return try {
val stream = context.contentResolver.openInputStream(uri)
val file =
File.createTempFile(
"${name}_${System.currentTimeMillis()}",
".jpg",
context.cacheDir
)
FileUtils.copyInputStreamToFile(stream, file) // Use this one import org.apache.commons.io.FileUtils
file
} catch (e: Exception) {
e.printStackTrace()
null
}
}
and a dependency in gradle :
implementation group: 'commons-io', name: 'commons-io', version: '2.7'
implementation group: 'org.apache.commons', name: 'commons-text', version: '1.9'

Upload Image to Server using Multipart and Request Body in Android in Kotlin

I am stuck in between a strange issue of uploading image file to server. Although I did upload file several times before, but this time I don't understand what is the issue.
I get the file path of respective file but RequestBody returns null. Below I mentioned what library I'm using.
I am using kotlin, MultiPart and RequestBody for file upload.
implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
implementation 'com.squareup.okhttp3:logging-interceptor:4.9.1'
Below is my code which I wrote for file upload. In which you can see GalleryCameraUtility.getImageRequestBody(imageFile) returns null for file.
File path from mobile device /storage/emulated/0/DCIM/Screenshots/test_image.jpg
fun addNewCompany(companyName: String, email: String,imageFile: File, ownerName: String, address: String, companyDetails: String){
val companyNameBody: RequestBody = companyName.toRequestBody("text/plain".toMediaType())
val emailBody: RequestBody = email.toRequestBody("text/plain".toMediaType())
val fileData: RequestBody? = GalleryCameraUtility.getImageRequestBody(imageFile)
val ownerNameBody: RequestBody = ownerName.toRequestBody("text/plain".toMediaType())
val addressBody: RequestBody = address.toRequestBody("text/plain".toMediaType())
val userIdBody: RequestBody = PreferenceHelper.readUserIdPref(Constants.USER_ID).toString()
.toRequestBody("text/plain".toMediaType())
addCompanyRepo.addNewCompanyApi(companyNameBody, emailBody, fileData, ownerNameBody, addressBody, userIdBody)
}
class GalleryCameraUtility {
companion object{
fun getImageRequestBody(sourceFile: File) : RequestBody? {
var requestBody: RequestBody? = null
Thread {
val mimeType = getMimeType(sourceFile);
if (mimeType == null) {
Log.e("file error", "Not able to get mime type")
return#Thread
}
try {
requestBody = sourceFile.path.toRequestBody("multipart/form-data".toMediaTypeOrNull())
/*MultipartBody.Builder().setType(MultipartBody.FORM)
.addFormDataPart(serverImageKey, uploadedFileName,sourceFile.asRequestBody(mimeType.toMediaTypeOrNull()))
.build()*/
} catch (ex: Exception) {
ex.printStackTrace()
Log.e("File upload", "failed")
}
}.start()
return requestBody;
}
// url = file path or whatever suitable URL you want.
private fun getMimeType(file: File): String? {
var type: String? = null
val extension = MimeTypeMap.getFileExtensionFromUrl(file.path)
if (extension != null) {
type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension)
}
return type
}
}
}
I spent so many hours on this but not able to find solution. Please help me out on this.

I can't find the files I uploaded to Google Drive

I'm trying to upload a file to Google Drive using Google Drive REST API v3. After the upload process is completed, it returns a status code of 200 (successful). But I can't find the files in my Google Drive. Please tell me what am I doing wrong? I will really appreciate if you provide a proper illustration or better still code snippet while helping me with this problem of mine. I am really anticipating your answers.
I have tried following the documentation but I am still getting the same error. I have searched everywhere online and stackoverflow, but none seems to provide the solution to my problem.

After reading through this Files: create Documentation, I have finally fixed the problem. Unknown to me is that the files where being saved in the AppData folder created by my app. The AppData folder is hidden which can only be accessible by and through my app. For me to be able to save the file to My Drive folder, I removed the part of the metadata
` .append(',')
.append("\"parents\":").append("[\"").append(APP_FOLDER_ID).append("\"]")`
So the metadata part is now like this
val b = StringBuilder()
b.append('{')
.append("\"name\":\"").append(exportedFileName).append('\"')
.append(',')
.append("\"mimeType\":").append("\"text\\/csv\"")
.append('}')
val metadata = b.toString()
Every other thing remains the same
