ClientError: InvalidArgument when calling PutObject with django-storages==1.14.4

[Tariq628]

I am encountering a ClientError: InvalidArgument when attempting to upload files to an S3 bucket using django-storages==1.14.4. This issue did not occur with django-storages==1.10, where the file upload process worked seamlessly. The error message is as follows:

botocore.exceptions.ClientError: An error occurred (InvalidArgument) when calling the PutObject operation: None

I have an S3 bucket with proper permissions, and the relevant bucket policies and IAM roles are configured to allow s3:PutObject, s3:GetObject, and s3:PutObjectAcl. The bucket has been set with public read/write access, and the storage configuration uses the django-storages package with boto3. Despite this, the error persists in the newer version of django-storages.

The same file upload code works without issues on django-storages==1.10, which leads me to believe the issue may be related to changes introduced in the newer version. I would appreciate any insights or advice on how to resolve this error and whether there are any known issues or differences between the two versions that could be causing this problem.
