error writing path %v: %v

Error message

error writing path %v: %v

What it means

assetcopy's writeFile helper wraps vfs.Path.WriteFile failure after computing the ACL. It fires when copying a cluster asset to a VFS-backed destination (s3/gs/azure/blob) fails — permissions on the target, bucket errors, or connectivity — and is invoked by transferFile for both content and sha files.
