（boto3）An error occurred (InvalidArgument) when calling the CreateMultipartUpload operation

[TreHack]

When I use boto3（DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'），I get the below error. But when I use boto2（DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'），everything works well. Are there some bugs with boto3？？

I had this when I set default_acl to None instead of its default of 'public-read' (or the value I ended up setting, 'private')

[zbyte64]

Also had this when I set AWS_DEFAULT_ACL='public-read'

[pawl-bb]

This happened to me because I was using S3BotoStorage like FileSystemStorage and using the location as the first argument. Example: S3BotoStorage(LOCATION)

It turns out that acl is actually the first argument. So, it was sending the location as an ACL, which causes the InvalidArgument error.

I am running into this. Small files upload successfully but bigger files fail with this error.

I found this thread about the same issue happening in the AWS cli: https://github.com/aws/aws-cli/issues/1674 however it mentions it was fixed, and I still have the problem

[remram44]

The specific error from the DEBUG log:

Thanks for the error log. I'm still not sure what is going on.

Which way are you using it? Via the File or the Storage? I'm curious if one will work where the other fails. It's strange because all of the other issues I see with the same message appear to be either fixed or Google Cloud issues.

[remram44]

I'm filing this particular bug against boto3 directly, since the problem doesn't seem with django-storage itself: https://github.com/boto/boto3/issues/2207

Probably a Google Cloud incompatibility :cold_sweat: not hopeful to see a fix

[costela]

For future reference, it's possible to work around this issue by patching S3Boto3Storage._save and changing the upload_fileobj call to use boto3.s3.transfer.TransferConfig, e.g.:

MB=1024**2
obj.upload_fileobj(content, ExtraArgs=params, Config=TransferConfig(multipart_threshold=100 * MB))

Could this maybe be added as a setting? Might help people switching providers to GCP but wanting to keep the S3 API usage.

It's a bit unclear to me what are the downsides of forcing the non-multipart upload for bigger files. I see only the issue of broken big uploads needing to be retried from the start (as opposed to retrying from the failed chunk), but I may be overlooking some bigger issue.

[jschneier]

This is no longer relevant due to the GCP backend. Also, TransferConfig was added as a setting anyway.
