$ dandi ls --help

Usage: dandi ls [OPTIONS] PATH|URL

  List .nwb files and dandisets metadata.

  The arguments may be either resource identifiers or paths to local
  files/directories.

  RESOURCE ID/URLS:

   dandi commands accept URLs and URL-like identifiers called <resource  ids>
   in the following formats for identifying Dandisets, assets, and  asset
   collections.

   Text in [brackets] is optional.  A server field is a base API or GUI URL
   for a DANDI Archive instance.  If an optional ``version`` field is  omitted
   from a URL, the given Dandiset's most recent published version  will be
   used if it has one, and its draft version will be used otherwise.

  Accepted resource identifier patterns:
   - DANDI:<dandiset id>[/<version>]
   - https://gui.dandiarchive.org/...
   - https://identifiers.org/DANDI:<dandiset id>[/<version id>] (<version id> cannot be 'draft')
   - https://<server>[/api]/[#/]dandiset/<dandiset id>[/<version>][/files[?location=<path>]]
   - https://*dandiarchive-org.netlify.app/...
   - https://<server>[/api]/dandisets/<dandiset id>[/versions[/<version>]]
   - https://<server>[/api]/assets/<asset id>[/download]
   - https://<server>[/api]/dandisets/<dandiset id>/versions/<version>/assets/<asset id>[/download]
   - https://<server>[/api]/dandisets/<dandiset id>/versions/<version>/assets/?path=<path>
   - https://<server>[/api]/dandisets/<dandiset id>/versions/<version>/assets/?glob=<glob>
   - dandi://<instance name>/<dandiset id>[@<version>][/<path>]
   - https://<server>/...

Options:
  -F, --fields TEXT               Comma-separated list of fields to display.
                                  An empty value to trigger a list of
                                  available fields to be printed out
  -f, --format [auto|pyout|json|json_pp|json_lines|yaml]
                                  Choose the format/frontend for output. If
                                  'auto', 'pyout' will be used in case of
                                  multiple files, and 'yaml' for a single
                                  file.
  -r, --recursive                 Recurse into content of
                                  dandisets/directories. Only .nwb files will
                                  be considered.
  -J, --jobs INTEGER              Number of parallel download jobs.  [default:
                                  6]
  --metadata [api|all|assets]
  --schema VERSION                Convert metadata to new schema version
  --help                          Show this message and exit.

The 3.12 Test breaking is unrelated, its just a flake.

I bumped the timeout #1505 fwiw.

[asmacdo]

3.8 Test is also unrelated #1503
