Pickle load of joblib not working on Heroku

[Shahadate-Rezvy]

Hi, I followed one of your explainerdashboard example to deploy a heroku app. I trained my own model and done a dump of the processed model as joblib file. I am currently facing an error as attached, do you have any idea please why this is happening?
