How to authenticate to google_api_tool with service account json file

[AnnaBuchmanAP]

I'm trying to authenticate to SheetsToolset which is based on google_api_tool using a service account credential:

from google.adk.tools.google_api_tool import SheetsToolset
from google.adk.auth.auth_credential import ServiceAccount, ServiceAccountCredential

with open(credentials_path) as f:
    service_account_cred = json.load(f)

SERVICE_ACCOUNT_SCOPES = [
    "https://www.googleapis.com/auth/spreadsheets"
]
    
service_account_credential = ServiceAccountCredential(
    type_=service_account_cred.get("type"),
    project_id=service_account_cred.get("project_id"),
    private_key_id=service_account_cred.get("private_key_id"),
    private_key=service_account_cred.get("private_key"),
    client_email=service_account_cred.get("client_email"),
    client_id=service_account_cred.get("client_id"),
    auth_uri=service_account_cred.get("auth_uri"),
    token_uri=service_account_cred.get("token_uri"),
    auth_provider_x509_cert_url=service_account_cred.get("auth_provider_x509_cert_url"),
    client_x509_cert_url=service_account_cred.get("client_x509_cert_url"),
    universe_domain=service_account_cred.get("universe_domain"),
)
service_account = ServiceAccount(
    service_account_credential=service_account_credential,
    scopes=SERVICE_ACCOUNT_SCOPES
)
sheets_toolset = SheetsToolset(
    service_account=service_account,
    tool_filter=["sheets_spreadsheets_create",
                 ]
)

The error is: ERROR - fast_api.py:928 - Error in event_generator: OAuth2 credentials client_id is missing.
from google/adk/tools/openapi_tool/openapi_spec_parser/tool_auth_handler.py, line 203, in _request_credential
raise AuthCredentialMissingError(

I create adk ServiceAccountCredential with client_id.
Please help me: what am I doing wrong? Thanks!
