Aws::S3::Errors::InvalidArgument (): on bucket.put_object - ruby

Question

I'm trying to upload base64 encoded image to S3 bucket. My bucket list shows correctly after signing in. I'm trying to upload using the bucket#put_object
I don't see any hint as to what the invalid argument is.
My JSON body looks like..
""product": {
"product_photo": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAT8AAADQCAYAAABxw2ZIAAABQGlDQ1BJQ0MgUHJvZmlsZQAAKJFjYGASSCwoyGFhYGDIzSspCnJ3UoiIjFJgf8LAxsDMIAqEVonJxQWOAQE+QCUMMBoVfLvGwAiiL+uCzH ...."
and if I use the Carrierwave file storage, image saves fine.
How do I upload my base64 image using just the aws-sdk?

Answer 1

Enable wire trace to see what is being sent to S3 and what the responses are.

Answer 2

The allowed options for :acl according to documentation are private, public-read, public-read-write, authenticated-read, aws-exec-read, bucket-owner-read, bucket-owner-full-control.
So, you have to change public_read to public-read
obj = bucket.put_object({body: data, key: name, content_type:type,acl:"public-read"})
