finished with status code: 500
santhoshdc1590 opened this issue · 3 comments
I was successful in running the python code I want by deploying it on cloud function. 🎉🎉🎉🎉
This is my function.py file content.
from FTUL import mainP
from cloudfn.google_account import get_credentials
from cloudfn.http import handle_http_event, Response
from google.cloud import bigquery
import json
def handle_http(req):
biquery_client = bigquery.Client(credentials=get_credentials())
if req.method == 'POST':
#extract information from the body of the POST request
rBody = json.loads(req.body)
im = rBody['image']
rID = rBody['refID']
rTable = rBody['refTable']
# Do the required operation from the extracted info
mainP(im,rID,rTable)
return Response(
status_code=200,
)
handle_http_event(handle_http)
The cloud function runs as expected, but always ends with error code 500
When I check the logs of google.
this is what is being printed

Can anyone help me resolve the issue?
shimHandler inside index.js in cloudfn/template is returning 500

Can anyone help resolve this and explain what is happening here?
Finally found the error
@MartinSahlen You should mention this in the documentation I feel. python print statements cause these errors. So in order to run cloud-function-python on cloud-function avoid using print in python part of the code
