LastAccessed time to objects then are there any clients which will throw due to an unexpected key in the schema? But, like most R2 extensions to S3, they could just throw it in a custom header (or re-use Last-Modified).The specified bucket does not exist. (Code: 10006) error. I can create another custom domain on the bucket and it works fine.
