hi, i’ve been struggling to deploy my dash app to Heroku, getting the errors H13 and H10, has anyone seen these before? my directory is as per dash instructions -https://dash.plotly.com/deployment. just lost as to what the codes mean, from consulting forums, was guessing a bad Port or maybe need to run Heroku restart?
appreciate any help, cheers!
ps code runs fine locally, it’s a bit long but I can post if needed.
