Android Question [SOLVED] POST map and image (PostMultipart) to API

[ThePuiu]

I want to make a POST call to an API. In Postman I can make the call with the parameters:

http://api.xxxxxxxx.eu/api/uploadfile

form-data:
jsonKey = {"id":"1", "location":"home address"}
file = homepicture.jpg

I try with code:

Dim jobSend As HttpJob
   
Dim fd As MultipartFileData
fd.Initialize
fd.KeyName = "file"
fd.Dir = PathPHOTO
fd.FileName = NamePHOTO
fd.ContentType = "image/jpeg"
        
Dim flist As List
flist.Initialize
flist.Add(fd)

Dim NameValues As Map
NameValues.Initialize
NameValues.Put("id", "1")
NameValues.Put("location", "home address")

jobSend.Initialize("JobSend", Me)
jobSend.PostMultipart("http://api.xxxxxxxxx.eu/api/uploadfile",NameValues,flist)

something is wrong because the message received in JobDone is:
ResponseError. Reason: Not Acceptable, Response: "Object reference not set to an instance of an object."
I assume NameValues is not formatted correctly...

Can anyone help me with an idea?
Thank you!

You shouldn't have a JobDone sub.

I don't see any other error in your code. Is this the full error message?

there seems to be another error. I will post the full code, maybe it will be easier for you to find the answer ...

Sub CC_Result(Success As Boolean, Dir As String, FileName As String)
    If Success Then
        File.Copy(Dir, FileName, File.DirInternal, "sesizare.jpg")  
        ImageViewPoza.Bitmap = LoadBitmap(Dir.Internal, "sesizare.jpg")
    End If  
End Sub

Sub ButtonTrimite_Click
    Dim jobSend As HttpJob
       
    Dim fd As MultipartFileData
    fd.Initialize
    fd.KeyName = "file"
    fd.Dir = File.DirInternal
    fd.FileName = "sesizare.jpg"
    fd.ContentType = "image/jpeg"
           
    Dim flist As List
    flist.Initialize
    flist.Add(fd)
           
    Dim NameValues As Map
    NameValues.Initialize
   
    NameValues.Put("id", "1")
    NameValues.Put("location", "home address")

           
    jobSend.Initialize("JobSendSesizare", Me)
    ProgressDialogShow2("Asteptati va rog...", False)

    jobSend.PostMultipart("http://api.xxxxxxxx.eu/api/uploadfile",NameValues,flist)  
    jobSend.GetRequest.Timeout = 60000
   
    Wait For (jobSend) JobDone(jobSend As HttpJob)
    Dim data As String = jobSend.GetString
    jobSend.release
    Log(data)
    ProgressDialogHide
End Sub

error is:

ResponseError. Reason: Not Acceptable, Response: "Object reference not set to an instance of an object."

the error came from the server and not from the B4A code. The problem was solved!
