Stellar-core failing to initialize history archives to S3

Question

My archive setups are configured like this:

[HISTORY.v1]
get="aws s3 cp s3://my-bucket/v1/{0} {1}"
put="aws s3 cp {0} s3://my-bucket/v1/{1}"
[HISTORY.v2]
get="aws s3 cp s3://my-bucket/v2/{0} {1}"
[HISTORY.v3]
get="aws s3 cp s3://my-bucket/v3/{0} {1}"

When I run sudo stellar-core --newhist v1 I get the the following error:

Not sure what the issue could be since I manually tested uploading and downloading from the same bucket.
