You'll notice
upload_asset size-limit errors now include the actual file size in bytes
What
When the Artifact tool's upload_asset rejects a file for being too large, the error it throws now includes a sizeBytes field carrying the exact byte size of the file that was rejected, in addition to the existing error message.
Why
This gives more precise information about why an upload failed, useful for understanding exactly how far over the limit a file was rather than just seeing a generic size-limit message.
