Error message

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

What it means

Role creation within a group (roles.py:73) requires a non-empty group_id for the POST /organization/groups/{group_id}/roles path; a falsy value raises ValueError before the role_id body is transformed. This is the standard generated guard for nested resources.

Solutions

Populate group_id from the same code path that created/looked up the group
Validate both group_id and role_id before the call
Store verified group/role IDs together in one config object

Example fix

# before
client.admin.organization.groups.roles.create(group_id=gid, role_id=rid)

# after
if not gid or not rid:
    raise ValueError(f'need both ids, got group={gid!r} role={rid!r}')
client.admin.organization.groups.roles.create(group_id=gid, role_id=rid)

Defensive patterns

Strategy: validation

Validate before calling

if not group_id or not role_id:
    raise ValueError('group_id and role_id are both required')
client.admin.organization.groups.roles.create(group_id=group_id, role_id=role_id)

Type guard

def are_valid_ids(*ids: object) -> bool:
    return all(isinstance(i, str) and i.strip() for i in ids)

Prevention

Validate parent and child IDs together for nested resources
Keep group and role IDs in one config object to avoid divergence
Use keyword arguments to prevent swapped parameters

When it happens

Trigger: client.admin.organization.groups.roles.create(group_id='', role_id='role_123'); typical when the parent group ID is a separate variable that was never populated.

Common situations: Scripts that attach roles to groups looked up earlier where the lookup returned nothing; hard-coded group IDs removed during refactoring.
