Uploading file from Android emulator hits the api with no such file or directory found error

[sumchans]

I am using graphql_flutter package to upload files from my Android emulator to azure blob storage. The moment I click the button to upload I get the [Errno 2] No such file or directory: '\data\user\0\com.example.bol\cache\2616255d-5f60-429a-9755-7f4023ce8275\avatar2.jpg' error.

If I set the path of a file on my desktop manually then the upload works.

Here is graphql schema-

type Mutation {
     fileUpload(file: FileUpload): Result!     
}
input FileUpload {
     filePath: String
     fileName: String
     fileType:String
     fileExtension:String
     uploadedDate: String
     uploadedBy: String
}

type Result {
     status: Int
     error: String
     fileUrl: String
}

Here is my mutation widget on Flutter-

Mutation(
      options: MutationOptions(
        document: gql(fileUploadMutation),
        fetchPolicy: FetchPolicy.cacheAndNetwork,
      ),
      builder: (runMutation, result) {
        return OutlinedButton.icon(
          label: const Text('Submit'),
          onPressed: () async {
            String user = user.phoneNumber.substring(1);
            String filePath = user.avatarUrl.replaceAll('/', '\\');
            String fileName = File(user.avatarUrl).uri.pathSegments.last;
            String fileExtension =
                fileName.substring(fileName.lastIndexOf('.'));
            fileExtension = fileExtension.substring(1);
            runMutation(
              {
                'filePath': filePath,
                'fileName': fileName,
                'fileType': 'Profile Picture',
                'fileExtension': fileExtension,
                'uploadedDate': DateTime.now().toUtc().toString(),
                'uploadedBy': user
              },
            );
          },
        );
      },
    );

Here is python graphql server -

@mutation.field("fileUpload")
def resolve_fileUpload(_, info, file):
    file_path = file['filePath']
    file_name = file['fileName']
    file_type = file['fileType']
    file_extension = file['fileExtension']
    uploaded_by = file['uploadedBy']
    uploaded_date = file['uploadedDate']

    try:
        container_client = blob_service_client.get_container_client(
            file['uploadedBy'])
        if not container_client.exists():
            container_client.create_container()
            container_client.set_container_metadata(
                metadata={'Created_Date': uploaded_date})

        with open(file_path, "rb") as file:
            content_settings = ContentSettings(content_type='image/jpeg')
            metadata = {'File_Name': file_name, 'Uploaded_Date': uploaded_date, 'Uploaded_By': uploaded_by,
                        'File_Type': file_type, 'File_Extension': file_extension}
            result = container_client.upload_blob(
                name=file_name, data=file_path, metadata=metadata, content_settings=content_settings)

    except AzureException as e:
        if e.status_code == 200:
            return {
                "status": e.status_code,
                "error": "",
                "fileUrl": result.url
            }
        else:
            return {
                "status": e.status_code,
                "error": e.message,
                "fileUrl": result.url
            }
    else:
        return {
            "status": 200,
            "error": "",
            "fileUrl": result.url
        }

This looks like not package bug, but related to this error I get the [Errno 2] No such file or directory: '\data\user\0\com.example.bol\cache\2616255d-5f60-429a-9755-7f4023ce8275\avatar2.jpg' error.

But looks like this is dependent from your code?

I know that it wont be a package bug, I just dont know how to make this work. I was seeking help here.

[vincenzopalazzo]

I think it is better use stackoverflow for this?

[sumchans]

I already did. When I dont get any help from there, that's when I post here. https://stackoverflow.com/questions/76386931/how-to-upload-a-picked-file-from-the-android-emulator-to-a-graphql-api
