S3 storage truncated to 250000MB per object without error

We're facing an issue where object storage on S3 is being truncated to exactly 262144000000 bytes (strangely 250,000MB) without error. oCIS takes the upload without issue, processes it, pushes to S3 and then complains when you try and download it because the metadata doesn't match. We're storing everything on Wasabi S3 which has a single object limit of 5TB so no issues there.

We're running oCIS 6.6.1 and were hitting the same issue on oCIS 6.2.0 although there we also hit the nats max payload exceeded error mentioned in https://github.com/owncloud/ocis/pull/10377 which we believed was causing the problem.

Error on retrieval attempt is:

Upload for the same appears clean in the logs:
