Dify version

1.9.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

Install an Endpoint plugin and execute self.session.app.chat.invoke() in it. In my case, I used https://marketplace.dify.ai/plugins/yt-koike/cron.

✔️ Expected Behavior

The specified app should be invoked without errors. I tested that Dify 1.8.1 can execute self.session.app.chat.invoke() well.

❌ Actual Behavior

When the plugin executes invoke(), it returns an error which says Internal Server Error: invoke app failed: request failed with status code: 400 and respond with: {"code":"invalid_param","message":"user not found","status":400}.
In Dify's docker compose logs, Dify records the following error.

db-1 | 2025-09-26 12:03:15.082 UTC [1562768] ERROR: invalid input syntax for type uuid: "DEFAULT-USER" at character 471 
db-1 | 2025-09-26 12:03:15.082 UTC [1562768] STATEMENT: SELECT end_users.id AS end_users_id, end_users.tenant_id AS end_users_tenant_id, end_users.app_id AS end_users_app_id, end_users.type AS end_users_type, end_users.external_user_id AS end_users_external_user_id, end_users.name AS end_users_name, end_users.is_anonymous AS end_users_is_anonymous, end_users.session_id AS end_users_session_id, end_users.created_at AS end_users_created_at, end_users.updated_at AS end_users_updated_at
db-1 | FROM end_users
db-1 | WHERE end_users.id = 'DEFAULT-USER'::UUID AND end_users.tenant_id = '25633d38-cf86-4217-902a-8731d3152a6b'::UUID
db-1 | LIMIT 1

Regarding the log, I presume it is because Dify 1.9.0 does not have DEFAULT-USER anymore.
