iOS return 500 while using flutter uploader with version 1.x

[neohboonyee99]

For android the flutter uploader works fine, the server able to upload the data. But for iOS, I meet this issue.

Then, I have tried the flutter uploader with version 3.0 beta, it didn't appear this error, but it straight went into this line first and the progress automatically = 100 uploader.result.listen((result) { BotToast.showText(text:"Complete"); } instead of this uploader.progress.listen((progress) { BotToast.showText(text:progress.progess.toString()); }

then it automatically run 2nd time ( uploader.enqueue() ) then start from listening the progress=0. When the progress =100 and result = UploadTaskStatus.complete , it did toast the complete but my server couldn't receive any data from it.

have you checked that the issue is not the content-type header? we had the same issue (server not receiving anything when the request came from iOS but worked fine on android) and setting no content-type header worked for MultipartFormDataUpload Related issue #204

@neohboonyee99 @brianegan @ened @raphaelgurtner what does setting no content-type header means? Can you please tell me what to write? Here is my code:

await FlutterUploader().enqueue(
                    RawUpload(
                      url: uploadUrls[i],
                      // required: url to upload to
                      path: selectedVideos[i].path,
                      // required: list of files that you want to upload
                      method: UploadMethod.PUT,
                      // HTTP method  (POST or PUT or PATCH)
                      // headers: {"apikey": "api_123456", "userkey": "userkey_123456"},
                     //I have also tried uncommenting this headers property and also tried adding "content-type": ""
                      tag: 'post video uploading', // custom tag which is returned in result/progress
                    ),
                  );

I have also tried uncommenting this headers property and also tried adding "content-type": "". but I still keep getting this:
