Error: django.utils.datastructures.MultiValueDictKeyError: '1'

[fabian-ws]

Hello Imcgartland,

I've been busy all day with trying to upload an image to django by react-native. After reading a lot I landed at graphene-file-upload. Unfortunately, I do not get it to work and I hope you can help.

I get the following error message:

On the client-side I´m using 'apollo-upload-client' as described on their page.

I can see in the debugger that the error occurs in this function: (graphene_file_upload/utils.py)

def place_files_in_operations(operations, files_map, files):
    """Replaces None placeholders in operations with file objects in the files
    dictionary, by following the files_map logic as specified within the 'map'
    request parameter in the multipart request spec"""
    path_to_key_iter = (
        (value.split('.'), key)
        for (key, values) in iteritems(files_map)
        for value in values
    )
    # Since add_files_to_operations returns a new dict/list, first define
    # output to be operations itself
    output = operations
    for path, key in path_to_key_iter:
        file_obj = files[key]
        output = add_file_to_operations(output, file_obj, path)
    return output

-> file_obj = files[key]

the files array is empty.

Do you have an idea what I´m doing wrong?

Hey @fabull86 can you solve that error?

I'm evaluating this library. I wanted to know if it is stable considering that my application will use a lot of image uploads.

Hey here, any intention to merge the PR to solve this problem?

[Delvio]

any workarounds for this issue?

[delegacy]

Same here. When would #66 be released?

[rukna123]

Yes guys, I'm on v1.3.0, and it's still throwing same error. When would https://github.com/lmcgartland/graphene-file-upload/pull/66 be released? @delegacy did you find any other way to get around this?

    output = operations
    for path, key in path_to_key_iter:
        file_obj = files.get(key, None)
        output = add_file_to_operations(output, file_obj, path)
    return output

This solves the problem for me.
