What went wrong?

Likewise, https://openneuro.org/datasets/ds005126/file-display/participants.tsv appears as:

The files appear to be good on the server:

/datasets/ds005126$ file participants.*
participants.json: JSON text data
participants.tsv:  ASCII text, with CRLF line terminators

Expected behavior

This is fixed for this dataset but still investigating the cause. The issue is that non-existent versions were recorded for the annex keys, so invalid S3 URLs were generated. This isn't draft specific but it was also only a subset of objects (some were fine). It's possible it is an interrupted export but not a failure case we've seen before.
