After moving to a new bucket-name for Project B, I was unable to upload any object despite having a seemingly OK policy attached to my bucket.
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "statement1",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::AccountB-ID:user/jack"
},
"Action": ["s3:PutObject","s3:PutObjectAcl"],
"Resource": "arn:aws:s3:::projectb"
}
]
}
The fix? In the line "Resource" I needed to add a star after the bucketname in order for the putObject to work and allow me to upload entities into the bucket.

"Principal": {
"AWS": "arn:aws:iam::AccountB-ID:user/jack"
},
"Action": ["s3:PutObject","s3:PutObjectAcl"],
"Resource": "arn:aws:s3:::projectb/*"
}
]
}
