I have, for example, this function
I deployed it with VS Code using the following F1 option in VS Code
Nonetheless, when I go to the function app portal, it shows nothing under the functions submenu:
I don't know why I am not being able to see my functions in my function app, what am I missing?
Here is the dummy code of the function:
import azure.functions as func
import logging
import os
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
from azuremunication.email import EmailClient
from datetime import timezone, timedelta, datetime
import jwt
import bcrypt
import pymssql
import json
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
@app.route(route="actualizar_contrasena", auth_level=func.AuthLevel.ANONYMOUS)
def actualizar_contrasena(req: func.HttpRequest) -> func.HttpResponse:
import json
try:
req_body = req.get_json()
username_to_check = req_body.get("username")
password_to_check = str(req_body.get("password"))
# do things
return func.HttpResponse(
json.dumps(
{"access_token": 1, "refresh_token": 1}
),
status_code=200,
)
except Exception as e:
return func.HttpResponse(str(e), status_code=500)
UPDATE
After following @RithwikBoj instructions, I'm in the same situation. I have observed that locally I can't see the functions neither:

I realised that the requirements.txt has something wrong with it in the Function App
And the folder structure has not been updated, because I removed the Readme.md a while ago:
UPDATE I have edited the yaml, now it uploads the requirements.txt file correctly
UPDATE 2
I have deleted all imports except os, logging and azure.functions. After that, I can deploy correctly my function. Butm when I for example add import jwt to the python script, it disappears again. I need to add libraries to the script, that is my main issue
UPDATE 3 Adding the import inside the definition of each function seems to work:

- Can you edit your question to share an minimal reproducible example of how you’ve defined your function(s) you expect to appear in the portal? – esqew Commented Jan 15 at 19:22
- hi @esqew, i'm expecting to be able to see and click my function "actualizar_contrasena" in the azure portal. as you can see in the screenshot, it isn't there. just in my local function – OK 400 Commented Jan 15 at 22:09
- @esqew I have added my code, but I don't think it is needed in my question – OK 400 Commented Jan 15 at 22:13
- Added all packages in requirements.txt file? – RithwikBojja Commented Jan 16 at 3:30
- I have added all of them indeed @RithwikBojja – OK 400 Commented Jan 16 at 18:15

Reset to default 4 +400Regarding your UPDATE 3
The error message is clear that jwt package is not installed.
You already have jwt in the requirements.txt, the issue is in the github yaml pipeline. The build step activats virtual env and installs packages into the virtual env. However, your zip step excludes these venv\*. This is the reason the python packages do not exist on function app when you invoke the http trigger.
- name: Create and start virtual environment
run: |
python -m venv venv
source venv/bin/activate
- name: Install dependencies
run: pip install -r requirements.txt
# Optional: Add step to run tests here
- name: Zip artifact for deployment
run: zip -r release.zip function_app.py host.json -x "*.txt venv/*" ".git/*" ".github/* *.md .gitignore local.*"
To validate if jwt is really installed or not on FA, you can browse files using vs code
The reason moving import jwt into log_in_user worked is that this function is not invoked until a http trigger is executed. when you put import jwt on the top of the file, this line is executed during function startup.
Deploy python function app to Azure via CMD
There are a few ways to deploy a python function, let's try this method first to test it out. This method gives you most visibility of what is happening under the hood.
- Go to root of the project locally
- Delete .venv folder. this is to speed up package time, we dont need virtual env for azure function. otherwise the whole folder will be zip and unzip and causes issues.
- Run
func azure functionapp publish <function app name>ingit bashor any terminal window. i.e.func azure functionapp publish test3339 - if error asking you to upgrade pip, please do so
- watch the log. basically it should upload files, and do a remote build
- Once completed, go to the
deploymenttab under function app to see the final status of deployment to be sure:
- It might take 30 seconds for the function to show up in the overview page
This is a great guide to read through. the cmd deployment is under Deploy the function project to Azure section.
https://learn.microsoft/en-us/azure/azure-functions/create-first-function-cli-python?tabs=windows%2Cbash%2Cazure-cli%2Cbrowser
Deploy python function app to Azure via GitHub
If confirmed working in above method, you can refer to this guide to setup github action to deploy via pipeline. It is important to add venv to .gitignore so that these files are excluded from repo (also pipeline build)
https://learn.microsoft/en-us/azure/azure-functions/functions-how-to-github-actions?tabs=linux%2Cpython&pivots=method-manual
Python virtual env
when you run the func start locally with virtual env, the python packages are installed to system folder.
You have the option to create virtual env and active it to keep local python env clean. this is the purpose of .venv folder. I think VS Code by default creates one for your project.
py -m venv env
.\env\Scripts\activate
But when deploying to Azure, the build process will install all the packages for you and it does not use the virtual env inside .venv folder.
I have used below code and it got deployed for me and followed below process:
function_app.py:
import azure.functions as func
import logging as ri_lg
import pymssql as chop
from azure.identity import DefaultAzureCredential
from azure.keyvault.secrets import SecretClient
rith = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)
@rith.route(
route="rith_func", methods=["POST"], auth_level=func.AuthLevel.ANONYMOUS
)
def rith_func(req: func.HttpRequest) -> func.HttpResponse:
try:
rith_rq_bdy = req.get_json()
eml = rith_rq_bdy.get("email")
pwd = rith_rq_bdy.get("password")
ri_con = chop.connect(server="rithwik.database.windows",user="rithwik",password="RTestpass@2",database="test1")
cho_cur = ri_con.cursor()
cho_cur.execute("UPDATE users SET password = %s WHERE email = %s",(pwd, eml))
ri_conmit()
return func.HttpResponse("Hello Rithwik, the Password has been updated",status_code=200)
except Exception as f:
ri_lg.error(f"Error: {f}")
return func.HttpResponse(f"Hello Rithwik, there is an error: {f}",status_code=500)
finally:
if "ri_con" in locals() and ri_con:
ri_con.close()
