ConversationHandler not working when deployed on Heroku but is working good when running on local machine - python-telegram-bot

Question

I am using Python Telegram Bot library to make a bot that has a conversation which let's users name their project, payment plans etc. The conversation consists of MessageHandlers and CallBackQueryHandlers. Thr problem I'm facing is, this conversation was working fine when I was using this bot from my local machine, but when I deployed it to heroku, I can't have the full conversation, it would become unresponsive at some point and I would have to cancel the conversation(which surprisingly, works at lightning bolt speed). All other handlers of my application work as expected and respond quickly.
I am using webhook in this application.
The ConversationHandler:
add_project_handler = ConversationHandler(
entry_points=[CallbackQueryHandler(project_name, pattern="add_project")],
states={
PROJECT_NAME: [MessageHandler(Filters.regex(".*"), store_name_maybe_project_type)],
PROJECT_TYPE: [CallbackQueryHandler(store_type_maybe_admin)],
ADMIN:[CallbackQueryHandler(connect_channel)],
CONNECT:[MessageHandler(Filters.regex(".*"), connect_channel_add_currency)],
CURRENCY:[CallbackQueryHandler(store_currency_maybe_frequency)],
FREQUENCY:[CallbackQueryHandler(store_frequency_maybe_amount)],
MONEY:[MessageHandler(Filters.regex(".*"), store_amount_maybe_bot)],
TOKEN:[MessageHandler(Filters.regex(".*"), store_bot_show_links)],
PAY_SETUP:[CallbackQueryHandler(setup_payment)],
PAYPAL:[MessageHandler(Filters.regex(".*"), handle_client_id)],
CLIENT_ID:[MessageHandler(Filters.regex(".*"), handle_client_secret)],
},
fallbacks=[CommandHandler('cancel', cancel)],
)
handlers.append(add_project_handler)
EDIT:
So I checked out the logs, and I saw some really weird behavior, so it recieves an update, and right now, the state of the conversation should have been 1, but it says 'selecting conversation with state None'. That too it does three times.

And here's something more weird, when I click the button twice rapidly, it takes me to the next state.

I don't understand why it worked fine when I ran it on my own machine, but does this on heroku.
Additional Information -
These are the functions that are involved in this log:
def store_type_maybe_admin(update, context):
# Open db connection
conn = DB_POOL.getconn()
cur = conn.cursor()
# stores project type and conditonally asks for making admin
query = update.callback_query
query.answer()
keyboard = [[InlineKeyboardButton("Done", callback_data="channel_done")]]
reply_markup = InlineKeyboardMarkup(keyboard)
if query.data != "channel_done":
context.user_data["project_type"] = query.data
q = "UPDATE project SET project_type = %s WHERE id = %s"
cur.execute(q, (query.data, context.user_data["project_id"]))
conn.commit()
message = f"Please create a private Telegram {query.data} and click Done when it's ready:"
video = "BAACAgUAAxkDAAICCGFK8ud7FDZ2qbzOkQfrDId-abgXAAKqAwAC-KBYVquzwMps2x7GIQQ"
return_value = PROJECT_TYPE
else:
message = "Please add this bot (#InviteMemberFiverrBot) to the channel admins. It needs Add Subscribers permission.\n\nPress Done when it's ready:"
video = "BAACAgUAAxkDAAICFmFK9GB185nfUvTeE6P3ZTnEp1YEAAKxAwAC-KBYVtfAgpeMwSB0IQQ"
return_value = ADMIN
# Send a video
context.bot.send_video(chat_id=update.effective_chat.id, video=video)
context.bot.send_message(chat_id=update.effective_chat.id ,text=message, reply_markup=reply_markup, parse_mode="markdown")
DB_POOL.putconn(conn)
return return_value # will be either PROJECT_TYPE = 1 or ADMIN = 2
def connect_channel(update, context):
query = update.callback_query
query.answer()
video = "BAACAgUAAxkDAAICGWFK9ShTxKcIN32o9njkIQMCXcwoAAKyAwAC-KBYVi7hYk0auE7IIQQ"
context.bot.send_video(chat_id=update.effective_chat.id, video=video)
context.bot.send_message(
chat_id=update.effective_chat.id,
text=f"To connect the channel, please forward a message (any) from the channel to this bot."
)
return CONNECT
This is how I have setup my bot:
bot = telegram.Bot(token=TOKEN)
dispatcher = setup(bot, db_pool)
#app.route(f"/{TOKEN}", methods=["POST"])
def respond():
"""Run the bot."""
update = telegram.Update.de_json(request.get_json(force=True), bot)
dispatcher.process_update(update)
return "ok"
the setup function:
def setup(bot, db_pool):
# Create bot, update queue and dispatcher instances
dispatcher = Dispatcher(bot, None, workers=0)
##### Register handlers here #####
initialize_bot_handlers = initialize_bot(db_pool) # initialize_bot returns a list of handlers
for handler in initialize_bot_handlers:
dispatcher.add_handler(handler)
return dispatcher
The conversation handler is inside the initialize_bot function.
