Why can't Cloud Function access metadata server in Vertex AI example? - google-cloud-functions

I followed this Vertex AI tutorial. However, at the last step, as the Cloud Function calls the prediction endpoint, it gets this failure.
This means it could not even access the metadata server. I.e., is not a permissions failure (though I did check that the myproject#appspot.gserviceaccount.com service account does have Project Editor role as specified). It is also an error strictly in Functions and IAM, not in Vertex.AI or other ML systems.
What is going wrong here?
Function execution took 673 ms, finished with status code: 500

Using multiple gunicorn workers cause the error with status PGRES_TUPLES_OK and no message from the libpq

I have a Flask website that uses the peewee ORM. The connection is managed by FlaskDB.
When I only use 1 gunicorn worker, it works well. But as soon as I use 2 or more gunicorn workers, I start getting this error:

peewee.DatabaseError: error with status PGRES_TUPLES_OK and no message from the libpq
The peewee documentation states that the connection should be thread-safe, but it seems there are thread-safety issues here.
I use playhouse.pool.PooledPostgresqlDatabase if that matters.
What is the solution to this problem?
I believe this is possibly due to the connection being opened before the workers are forked. I'm not too familiar w/gunicorns worker model, but googling your error reveals similar problems w/multiprocessing. Specifically,
When a program uses multiprocessing or fork(), and an Engine object is copied to the child process, Engine.dispose() should be called so that the engine creates brand new database connections local to that fork. Database connections generally do not travel across process boundaries.
That is for SQLAlchemy, but the same should apply to Peewee. Just ensure that all your connections are closed (pool.close_all()) when your workers first start running. Or similarly, if you're opening any database connections at module scope, ensure you call close_all() after using them. This way when your workers start up they will each have an empty pool of connections.
db = FlaskDB(app)
# ...
db.database.close_all()

Google Cloud Function error "OperationError: code=3, message=Function failed on loading user code"

The problem stems from your terminal commands not being properly formatted.

i tried a solution (given below , taken from the link https://bugs.mysql.com/bug.php?id=66030&thanks=3&notify=195). but it didn't help. I still get the same error. Please help me.
solution:
// We'll need some help from you to diagnose this one. With a text editor, open the /Applications/MySQLWorkbench.app/Contents/PlugIns/db_mssql_grt.py file
and around line 174 you'll find a line that looks like:
ver_string = execute_query(connection, "SELECT SERVERPROPERTY('ProductVersion')").fetchone()[0]
Change that to:
ver_string = execute_query(connection, "SELECT CAST(SERVERPROPERTY('ProductVersion') AS VARCHAR)").fetchone()[0]
Then save and retry. Thanks! //

anyone happen to see same problem?Could you please give me some suggestion.
all ,nothing wrong with mysql, and Django. It's for I use a complex SQL to access mysql:
SELECT *
FROM
(SELECT *,
#batch_rank := IF(#current_batch = spider , #batch_rank + 1, 1) AS batch_rank,
#current_batch := spider
FROM deja_crawler.crawl_batch_record
where spider in (select distinct spider from deja_crawler.crawl_batch_record where spider like '%_new' or spider like '%_update')
ORDER BY spider, create_time DESC)
ranked
WHERE batch_rank <= 3
the tables used to have not too much data, so it works, later, the table became huge, and the access time cost is almost 30s, but the connection time out is set as 20s, so it will raise time out error.

Installation of Indivo Database - Errors during Testing Indivo Backend Server

I am a Computer Engineering UG student, working on a research project on Explanation of Health Data. For my project, I am required to access the Indivo health database. I am running Ubuntu 14.10 in Oracle's VirtualBox, with my host laptop OS in Windows 8.1.
I completed all steps of installation as per the instructions here - http://docs.indivohealth.org/en/2.0/howtos/install-ubuntu.html. Out of the three options, I have installed MySQL for database.
But I am stuck while Testing backend server. I am always receiving two errors -

For my setup also I have seen the same error and I have contacted their google group and found that we can silently ignore that error and go ahead and see the things actually works or not. Mine is working fine eventhough i came across that errors.
