Error message

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

What it means

The sync `retrieve` of the admin model permissions resource requires a non-empty `project_id` for the GET to `/organization/projects/{project_id}/model_permissions`. The SDK raises this ValueError before the request when the value is falsy.

Solutions

  1. Print or log project_id before the call
  2. Check the config key or CLI argument that supplies it
  3. Load the id from projects.list()/create() responses instead of manual entry
  4. Fail fast at startup if required ids are absent

Example fix

# before
perms = client.admin.organization.projects.model_permissions.retrieve(project_id)

# after
assert project_id, "project_id must be set"
perms = client.admin.organization.projects.model_permissions.retrieve(project_id)
Defensive patterns

Strategy: validation

Validate before calling

if not project_id:
    raise ValueError("project_id required to read model permissions")

Type guard

def valid_project_id(v: object) -> TypeGuard[str]:
    return isinstance(v, str) and v.strip() != ""

Try / catch

try:
    perms = ...model_permissions.retrieve(project_id)
except ValueError as e:
    if "project_id" in str(e):
        raise ConfigError(str(e))
    raise

Prevention

When it happens

Trigger: Calling `model_permissions.retrieve(project_id='')` while trying to read which models a project can access, with an id variable that was never populated.

Common situations: Scripts parameterized by project where the argument was not passed, or reading the id from a YAML/JSON config with a typo'd key.
