Error message

Expected a non-empty value for `group_id` but received {group_id!r}

What it means

The sync project Groups `retrieve` method requires a non-empty `group_id` for the path `/organization/projects/{project_id}/groups/{group_id}`. The SDK raises this ValueError when group_id is '', None, or whitespace, before any request is sent.

Solutions

  1. Use the group's id, obtainable from groups.list output
  2. Guard lookups with an explicit check and clear error message
  3. Refresh cached group id mappings periodically

Example fix

# before
client.admin.organization.projects.groups.retrieve(project_id=pid, group_id=data.get("group"))

# after
gid = data.get("group")
if gid:
    client.admin.organization.projects.groups.retrieve(project_id=pid, group_id=gid)
Defensive patterns

Strategy: validation

Validate before calling

gid = data.get("group_id")
if not gid:
    raise ValueError("group_id is required")
client.admin.organization.projects.groups.retrieve(project_id=project_id, group_id=gid)

Type guard

def is_valid_group_id(v: str | None) -> bool:
    return isinstance(v, str) and bool(v.strip())

Try / catch

try:
    g = client.admin.organization.projects.groups.retrieve(project_id=pid, group_id=gid)
except ValueError as e:
    logger.error("bad group_id %r: %s", gid, e)
    return None

Prevention

When it happens

Trigger: Calling groups.retrieve with group_id from a lookup that returned None; passing a group name instead of its id (e.g. 'grp_abc123').

Common situations: Confusing group name with group id; blank fields in data driving lookups; stale mappings after group deletion.
