Image works fine locally but not on Heroku

Hey Guys,

Images aren’t working in my app when deployed to Heroku while everything works fine locally. As an example I made a simple app to display an image:

app = dash.Dash()
server = app.server

app.layout = html.Div(
    dbc.Card([
        html.P("test"),
        dbc.CardImg(src=app.get_asset_url('placeholder.jpg'))
    ])
)

Locally it works as intended:

But on Heroku it does not:

fails541×504 11.2 KB

I’ve put the assets folder and its contents in GIT so that can’t be the reason the Assets folder is not being found by Heroku. Also note that there are 8 images in my Assets folder even though one only is shown under Resources. (smart loading?)

Anyone has an idea what I could be doing wrong?
