I have a Python Azure Function App. I'm deploying the code via Github actions and have python-pptx in my requirements.txt, but when it's deployed, I get this error:

Use below code to import ppt module and create PowerPoint presentation.

function_app.py:

import azure.functions as func
import logging
from assets.powerpoint import PPTManager
logging.basicConfig(level=logging.INFO)
app = func.FunctionApp()

@app.route(route="http_trigger", methods=["get", "post"])
def http_trigger(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    try:
        ppt_manager = PPTManager()  # Create an instance of PPTManager
        logging.info("PPTManager instance created successfully.")
        
        ppt_filename = ppt_manager.create_presentation()  # Create a PowerPoint file
        logging.info(f"PowerPoint file created at: {ppt_filename}")
        logging.info('Python HTTP trigger function processed a request.')
        return func.HttpResponse("Presentation created successfully", status_code=200)
    except ImportError as e:
        logging.error(f"Error importing PPTManager: {str(e)}")
        return func.HttpResponse(f"Error importing PPTManager: {str(e)}", status_code=500)
    except Exception as e:
        logging.error(f"An error occurred: {str(e)}")
        return func.HttpResponse(f"An error occurred: {str(e)}", status_code=500)

try:
    logging.info("pptx imported successfully")
except ImportError as e:
    logging.error(f"Error: {str(e)}")
    print(f"Error: {str(e)}")

assets=>powerpoint.py:

        title = slide.shapes.title
        subtitle = slide.placeholders[1]

        title.text = "Hello, World!"
        subtitle.text = "Welcome to Azure Functions with PowerPoint"

        ppt_filename = "/tmp/sample_presentation.pptx"
        prs.save(ppt_filename)

            return prs.slides
        except Exception as e:
