Heroku completely ignores config.toml file

Question

I just made my website using streamlit and have uploaded it to heroku. I have a config.toml file in the.streamlit folder, which changes the text colour and background colour of the website.

On running it by using the streamlit run command, it works perfectly fine. But using heroku and going to the provided website, the text colour there seems to be black and the background white, which are not the correct colours.

Here is my setup.sh file:

mkdir -p ~/.streamlit/

echo "\
[general]\n\
email = \"myname@domain.com\"\n\
" > ~/.streamlit/credentials.toml

echo "\
[server]\n\
headless = true\n\
enableCORS=false\n\
port = $PORT\n\
" > ~/.streamlit/config.toml

Here is my config.toml file:

[theme]
primaryColor = '#eb4034'
backgroundColor = '#021d24'
secondaryBackgroundColor = '#B9F1C0'
textColor = '#FFFFFF'
font = "sans serif"

Here is my config.toml file

I'm not sure where that content comes from, but it won't be in your config.toml on Heroku because you create or overwrite that file in your setup.sh .

echo ing stuff and redirecting it into a file using > overwrites what's already there.

If that file already exists (unlikely on Heroku, but I'm not familiar with Streamlit so maybe it gets generated somehow), change > to >> so you append to the existing file instead:

echo "\
[server]\n\
headless = true\n\
enableCORS=false\n\
port = $PORT\n\
" >> ~/.streamlit/config.toml  # <-- Here

Or, add the [theme] section to your setup.sh (note the change to single quotes around #FFFFFF ):

echo "\
[server]\n\
headless = true\n\
enableCORS=false\n\
port = $PORT\n\
\n\
[theme]\n\
primaryColor = '#eb4034'\n\
backgroundColor = '#021d24'\n\
secondaryBackgroundColor = '#B9F1C0'\n\
textColor = '#FFFFFF'\n\
font = 'sans serif'\n\
" > ~/.streamlit/config.toml
