composio.errors.EntityNotFoundError: Entity ID '12345' not found in Composio database
File "app.py", line 42, in fetch_entity
entity = client.get_entity(entity_id) # <-- triggers error
File "/usr/local/lib/python3.9/site-packages/composio/client.py", line 88, in get_entity
raise EntityNotFoundError(f"Entity ID '{entity_id}' not found") Why it happens
This error occurs when the Composio client requests an entity by ID that does not exist or has been deleted. It can also happen if the ID is malformed or the client is querying the wrong environment or project.
Detection
Catch EntityNotFoundError exceptions around Composio client calls and log the requested entity ID and environment to detect invalid or missing IDs before the app crashes.
Causes & fixes
The entity ID passed to the Composio client does not exist in the target environment.
Verify the entity ID is correct and exists in the Composio project environment before making the API call.
The client is configured to use the wrong environment or project, causing valid IDs to be unrecognized.
Check and correct the Composio client configuration to point to the intended environment and project.
The entity ID string is malformed or empty due to a bug in upstream code.
Add validation to ensure the entity ID is a non-empty, well-formed string before calling the Composio API.
Code: broken vs fixed
from composio import ComposioClient
client = ComposioClient(api_key='sk-incorrect')
entity_id = '12345'
entity = client.get_entity(entity_id) # triggers EntityNotFoundError
print(entity)import os
from composio import ComposioClient
client = ComposioClient(api_key=os.environ['COMPOSIO_API_KEY'], environment='production') # fixed config
entity_id = '12345'
# Validate entity ID before call
if not entity_id or not isinstance(entity_id, str):
raise ValueError('Invalid entity ID')
entity = client.get_entity(entity_id) # fixed: correct env and validated ID
print(entity)Workaround
Wrap calls to client.get_entity in try/except EntityNotFoundError and handle missing entities gracefully, e.g., by returning a default value or prompting for a valid ID.
Prevention
Implement strict validation of entity IDs and environment configuration at app startup and use integration tests to verify entity existence before production calls.
