Received "multipart/form-data" request with no "boundary".

Error message

Received "multipart/form-data" request with no "boundary".

What it means

Thrown by 'bin/repository unpublish' when the resolved repository set does not contain exactly one repository. Unpublish removes all feed stories and notifications a repository generated during import, so it deliberately acts on a single repository; passing zero, two, or more resolved repositories is rejected. Note that loadLocalRepositories() also filters to repositories hosted on the current device, so a valid name on the wrong device can resolve to zero and trigger this same error (with a locality rejection reason surfaced separately).

Solutions

1. Pass exactly one repository identifier (monogram like R123, callsign, or UUID) to the command.
2. If the name is correct but the count is still wrong, run the command on a device that actually hosts the repository (check Almanac bindings).
3. Quote arguments in scripts to prevent shell globs expanding into multiple repositories.

Example fix

# before
bin/repository unpublish R1 R2

# after
bin/repository unpublish R1

# Pass exactly one quoted identifier and verify it resolves locally:
if [ "$(echo $REPOS | wc -w)" -ne 1 ]; then echo 'need exactly one repository' >&2; exit 2; fi
bin/repository unpublish "$REPOS"

When it happens

Trigger: Running 'bin/repository unpublish' with no arguments, with multiple monikers ('bin/repository unpublish R1 R2'), or with one identifier that the device-locality filter removes because the repository is not served by this cluster device: count($repositories) !== 1 at PhabricatorRepositoryManagementUnpublishWorkflow.php:47 throws.

Common situations: Cleanups scripted against the wrong host (repository not local to this device); accidental glob expansion passing several repos; forgetting the repository argument entirely; typo'd monikers resolving to zero.
