How to deploy metabase enterprise edition to heroku

I’m not able to deploy metabase.jar file to heroku

Errors :
Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 90 seconds of launch

Hi @pdagar29
Which version of Metabase?
For questions about Enterprise Edition, you should email support metabase.com

Hi @pdagar29,
I am having the same issue. Were you able to solve it?
I also tried deploying the enterprise version on Heroku using docker (docker image downloaded here: https://hub.docker.com/r/metabase/metabase-enterprise/), but I am getting this error:
“”"
Starting process with command /app/run_metabase.sh
