TypeError: object function can't be used in await expression

Question

I have created an async function called add_reaction_tasks which maps specific function to dictionary keys. This function returns the dictionary to a variable called tasks which is located in the event on_raw_reaction_add.

The first issue is that tasks = await add_reaction_tasks() raises the following error: line 343, in _run_event await coro(*args, **kwargs).

The second one is when I try to access the dictionary, denoted by tasks, with the key which_trigger and the argument payload, the following error is raised:

'1' : await add_rules_messages_tasks, TypeError: object function can't be used in 'await' expression.

I have made sure that await is used where possible. Besides that, I am not sure what else I have to get done, to make this code work.

The code snippets:

1) the functions used in add_reaction_tasks

def display_messages_error(payload = discord.RawReactionActionEvent):
                            ...
async def add_rules_messages_tasks(payload = discord.RawReactionActionEvent):
                            ...
async def add_years_messages_tasks(payload = discord.RawReactionActionEvent):
                            ...
async def add_programming_languages(payload = discord.RawReactionActionEvent):
                            ...

2) add_reaction_tasks function

async def add_reaction_tasks():
    add_tasks = {
                    '0' : display_messages_error,
                    '1' : await add_rules_messages_tasks,
                    '2' : await add_years_messages_tasks,
                    '3' : await add_programming_languages
                }
    
    return add_tasks

3) on_raw_reaction_add event

@bot.event
@commands.bot_has_permissions(manage_roles = True)
async def on_raw_reaction_add(payload : discord.RawReactionActionEvent):
    role  = None
    guild = None
    # if the guild is server_name
    if payload.guild_id == server_id:
        guild = find(lambda g : g.id == server_id, bot.guilds)
    
    member = get(guild.members, id = payload.user_id)

    if not guild: return
    if not member: return

    which_trigger = 0 # 0 stands for invalid message id (should trigger display_message_error function)
    try:
        which_trigger = str(all_role_reaction_ids[str(payload.message_id)]) # <= looks weird, but works
        #print(f'\nwhich_trigger = {which_trigger}\n')
    except KeyError as err:
        print(f'KeyError: {err}')
        print('Invalid role-reaction message id')
        return

    tasks = await add_reaction_tasks()  # <= first error
    
    await tasks[which_trigger](payload) # <= second error

    return

Answer 1

Even though the last three functions in the dictionary are asychronous, removing the await before them, makes them function as normal and no errors are raised.

However, how can they be asychronously run since the await keyword is not used before them?

working code

async def add_reaction_tasks():
    add_tasks = {
                    '0' : display_messages_error,
                    '1' : add_rules_messages_tasks,
                    '2' : add_years_messages_tasks,
                    '3' : add_programming_languages
                }
    
    return add_tasks
