Error publishing map

[ncarboni]

I am having a bit of trouble trying to export or publish a map I created with cartoframes.
The ideal possibility would be to export in HTML directly, but my udnerstanding is that it is not possible (please correct me if I am wrong).
Alternatevely, I thought to publish it on carto, however I am getting the "UnauthorizedErrorException: Access denied".

What I am doing:

I simply created a map, created a custom API key, set the credentials in a json file following the form:

{
  "username": "MY_USERNAME",
  "api_key": "API_KEY"
}

and use the funciton publish without password. Here's the code:

from cartoframes.viz import Map, Layer, size_bins_style
from cartoframes.auth import set_default_credentials

set_default_credentials('creds.json')
map_vc = Map(Layer(gdf, size_bins_style('City_number')))
map_vc.publish(
    name='map_test',
    password=None,
    if_exists='replace'
)

However I get the error "UnauthorizedErrorException: Access denied"

Using the master password, I have the same issue

Any idea why it is happening? I am on a free plan, it is maybe due to that?
