Unable to proceed with the telegram bot with error use_context

Did you replace this constant with your own unique token?

For the following line:

updater = Updater(BOT_TOKEN, use_context=True)

you can just enter it as:

updater = Updater(BOT_TOKEN)

since the default value is not being changed to a new value.

Apparently this is a popular project. Have you attempted following the link provided here
