ValueError: max() arg is an empty sequence #161
Description
This is a new error in burst2stack for me. A vertex search shows all of the burst files should be available for the target date (2017-07-12). I am searching for all the bursts inside a simple rectangular box. It seems to crash when assembling the SAFE directory.
$ burst2stack --rel-orbit 81 --start-date 2021-07-11 --end-date 2021-07-13 --extent regular.json --pols VV --all-anns
Found 45 burst(s), comprising 1 SAFE(s).

It does seem to download everything (all 45 bursts as expected, all three XML files), but can't put it together at the end:
