I got an error on my Cloud Run, in my log it said Broken Pipe error, and when I check it which line that got an error on my Code, it on my db2.comit(). My cloud run always run well from 6 month ago without any error, but now got this error.
So here are the detail from the log.

I am trying to store some session data in Redis JSON, but I am running into the following error:

Any ideas on how I can solve this?
I have tried changing the port and the redis host, but I am still having the same error.
I have a table called city in PostgreSQL
CREATE TABLE CITY (
CITYID serial PRIMARY KEY,
CNAME VARCHAR (50) UNIQUE NOT NULL,
STATE VARCHAR (50) NOT NULL
);
When I use simple select with SQLAlchemy it works fine
query = session.query(models.City)
cities = query.all() #works fine
cities = session.execute("SELECT cityid, cname FROM city where cityid = 1").fetchall() # works fine
By doing above, I make sure that my session works fine and connecting the DB properly.
When I try to call a stored procedure in SQLAlchemy it is not working.
Here is my SP (Postgres)
create or replace procedure addcity(
cname varchar(20),
state varchar(20)
)
language plpgsql
as $$
begin
insert into city
(cname, state)
values (cname, state);
commit;
end;$$
Here is my SQLAlchemy code:
session.execute('CALL addcity (?, ?)', [('One', 'Two')])
The above code throws error as below:

(Background on this error at: https://sqlalche.me/e/14/f405)
When I checked SOF, most of the answers quoting the params as list of string. However, having strings inside the list as param didn't help either.
These are the library versions I have used:
fastapi==0.68.0
uvicorn==0.14.0
sqlalchemy_filters==0.12.0
SQLAlchemy==1.4.21
typing-extensions==3.10.0.0
Werkzeug==2.0.1
FastAPI-SQLAlchemy==0.2.1
Flask==2.0.1
Flask-SQLAlchemy==2.5.1
PyYaml
psycopg2-binary==2.9.1
As noted in a comment to the question, psycopg2 does not like the commit; in the SP. If you remove that then this will work with SQLAlchemy:
import sqlalchemy as sa
from sqlalchemy.orm import Session
engine = sa.create_engine("postgresql://scott:tiger#192.168.0.199/test")
with Session(engine) as session, session.begin():
session.execute(
sa.text("CALL addcity (:param1, :param2)"),
{"param1": "One", "param2": "Two"},
)
# automatically commits when the context manager exits (assuming no errors)
After #GordThompson and #AdrianKlaver asked some questions I have played around a bit and got this code as a solution
SP:
create or replace procedure addcity(
cname varchar(20),
state varchar(20)
)
language plpgsql
as $$
begin
insert into city
(cname, state)
values (cname, state);
# removed commit from the original SP
end;$$
Python code
cname = "Five"
state = "Six"
session.execute('CALL addcity (:cname, :state)', {'cname' : cname, 'state': state})
session.commit()
This works like a charm! Thanks #GordThompson and #AdrianKlaver. You guys saved my time!
I searched for this error a lot, but I only find some with more information behind that like "FATAL: ...". Mine has none. It only says
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError)
I have a postgres database inside a docker container that has set his port to the standard 5432.
I've created the container with the following command:
docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -p 5432:5432 -d postgres
It is clean so no database created. The API should automatically create them.
I'm using Pycharm IDE, maybe it has something todo with that.

EDIT 2:
If I use my local postgres database in docker i get this error. If I use my extern database from Heroku it works perfectly fine!
EDIT 3:
So apparently it won't work with my local docker postgres database. Now I am using my production database over heroku (so externally) and everything works with psycopg2. I didn't found the error why it won't let me use my local db but whatever.
Even though I can see that you are using default port, maybe this can help to somebody with the same problem.
For me the problem was in explicit port definition - as I'm running two different postgres DB and (both from containers), one of them I set to listen to 5433 port - and this gives me exact same problem, so instead
SQLALCHEMY_DATABASE_URL = "postgresql://postgres:password#localhost/fastapi"
I just put:
SQLALCHEMY_DATABASE_URL = "postgresql://postgres:password#localhost:5433/fastapi"
Problem solved right away.
So I have an image which I read the contents off of through .read() which is part of the UploadFile class and I believe it reads in bytes https://fastapi.tiangolo.com/tutorial/request-files/. To convert the bytes objects into bytea data type I used psycopg2.Binary() but I got an error message saying KeyError: '$fu'
This is my code for the portion that's reading off the bytes from the image and trying to store it in Postgresql through the bytea data type
image_array = []
for image in images_upload:
contents = await image.read()
image_array.append(contents)
# add image validation
for (permission, text, characteristics, image) in zip(p, c, t, image_array):

f"values('{permission}','{text}',"
f"'{characteristics}'"

f",'{psycopg2.Binary(image)}')")
await database.execute(query=query)
