How to fix No job functions found error while debugging Python Function App in local? I want to deploy a function but I can't because of this error.

Question

I have 3 functions -

1. get_keyvault_secret() - To get the email password stored in Key Vault.
2. send_email() - To create a MIMEMulitpart object and send an email to a recipient using the password received from the first function.
3. main() - orchestrate the complete process. Send the KV URI and the secretname to 1st function and sends the password and other attributes to the 2nd function.

I'll attach my code here as well.

How do I resolve this issue?

def send_email(sender_email, receiver_email, subject, body, smtp_server, smtp_port, password):
    message = MIMEMultipart()
    message['From'] = sender_email
    message['To'] = receiver_email
    message['Subject'] = subject

    message.attach(MIMEText(body, 'plain'))
    try:
        context = ssl.create_default_context()
        with smtplib.SMTP(smtp_server, smtp_port) as server:
            server.starttls(context=context)
            server.ehlo()

            server.set_timeout(10)
            server.login(sender_email, password)
            text = message.as_string()
            server.sendmail(sender_email, receiver_email, text)

            logging.info("Email sent successfully!")
            return func.HttpResponse("Email sent successfully!", status_code=200)
        
    except (smtplib.SMTPConnectError, smtplib.SMTPAuthenticationError, smtplib.SMTPDataError) as e:
        logging.error(f"SMTP Error: {str(e)}")
        return func.HttpResponse(f"SMTP Error: {str(e)}", status_code=500)
    
    except socket.timeout:
        logging.error("SMTP Connection Timeout")
        return func.HttpResponse("SMTP Connection Timeout", status_code=500)
    
    except Exception as e:
        logging.error(f"Error: {str(e)}")
        return func.HttpResponse(f"Error: {str(e)}", status_code=500)
    
    finally:
        server.close()

def main(req: func.HttpRequest) -> func.HttpResponse:
    try:
        payload_body = req.get_body()
        KVUri = f"assume_a_Key_Vault_URI"
        secretName = "assume_a_secretname"
        password = get_keyvault_secret(KVUri,secretName)

        smtp_server = "smtp.sendgrid.net"
        smtp_port = 587
        recipients = "assume_an_email_ID"
        sender = "assume_an_email_ID"
        subject = "Test Mail | Azure Functions | ADF Pipelines Status"
        body = f"This is a Test Mail sent from an Azure Functions app. {str(payload_body)}"    

        response = send_email(sender, recipients, subject, body, smtp_server, smtp_port, password)
        if response.status_code == 200:
            return response 
        else:
            error_message = f"Failed to send email. Status Code: {response.status_code}"
            return func.HttpResponse(error_message, status_code=500)
        
    except Exception as e:
        logging.error(f"Error: {str(e)}")
        error_message = f"Internal Server Error: {str(e)}"
        return func.HttpResponse(error_message, status_code=500)

Hi @Alpesh Patil - Thanks for reaching out, and posting on the MS Q&A. It looks like you've opted for v2 programming model which relies on Python Decorators being present to describe metadata about your functions to the host runtime. With decorators, the HTTP-triggered function would look as follows:

import azure.functions as func
import logging

app = func.FunctionApp()

@app.function_name(name="HttpTrigger1")
@app.route(route="hello", auth_level=func.AuthLevel.ANONYMOUS)
def test_function(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    return func.HttpResponse(
        "This HTTP triggered function executed successfully.",
        status_code=200
        )

I hope this helps. If you have any follow-up questions or encounter more issues, feel free to comment below.
