So I have written a script to summarize a few newsletters and send them to me in Telegram. The script itself works perfectly. Now I tried to run this script every morning at 7 via crontab on a Ubunutu Server. The Log File looks fine, every print() I used in the script shows up normally without errors, but the it doesn’t send the message.

My Crontab command:

00 12 * * * DISPLAY=:0 /usr/bin/python3 /root/data/App/Briefing/main.py >> /home/main.log &2>1

Python scripts:

main.py

import ai as AiHandler
import mail as MailHandler
import send as Telegram
import pandas as pd
from datetime import date
def start():
    files = MailHandler.scanEmails()
    files = AiHandler.summarize(files)

    print(files)

    data = pd.read_csv('checkpoint.csv', sep=';')
    checkpoint = createMsg(data)

    s = f"morgentliches Briefing vom {date.today().strftime("%d.%m.%Y")}".replace(".", "\.")

    s += "nnn ☕️ *Die* *Lage* *am* *Morgen* *\-* *Spiegel*nnn" + createMsg(pd.read_csv('spiegel.csv', sep=';'))

    s += "nnn ???? *Berlin* *\-* *Tagesspiegel* *Checkpoint*nnn" + checkpoint

    s += "nnn???? *Tech* *Update* *\-* *ManagerMagazin* nnn" + createMsg(pd.read_csv('manager.csv', sep=';'))  


    Telegram.sendMessage(s)
    

def createMsg(data):

    s = ""

    for i in range(5):

        thema = data['Thema'][i].replace('*', '\*')
        zsm = data['Zusammenfassung'][i].replace('*', '\*')

        s += "????t" + "*" + thema + "*" + "n"
        s += zsm + "n"
    
    s = s.replace("-", "\-")
    s = s.replace(".", "\.")
    s = s.replace("(", "\(")
    s = s.replace(")", "\)")
    #s = s.replace("*", "\*")
    s = s.replace("!", "\!")

    return s
start()

send.py

import telebot

def sendMessage(msg):
    bot = telebot.TeleBot("7227173154:AAG_mXCBqa_lBsOYQ9uqz52GhRQu90AoDJA")
    bot.send_message(chat_id="@morgenbriefing", text=msg, parse_mode="MarkdownV2")

I tried adding DISPLAY:=0 to the crontab command but it didnt help
