Strapi admin password invalid immediately after creation with Heroku deployment

System Information
  • Strapi Version: 4.25.1
  • Database: Heroku PostgresSQL
  • Node Version: v20.15.1
  • NPM Version: 10.8.2

As the title suggests I’m running into issues with my deployed Strapi app in Heroku using Heroku’s postgresql database.
I’ve just created my admin user, account creation was successful, and I was logged in. To test the password I logged out and attempted to log back in. I got an “Invalid credentials” message when trying to login. I am certain my password is correct as I saved it to a password keychain.

I then reset the password using the suggestion from this post - I forgot my strapi admin email and password deployed in heroku. Did not receive any errors when running this script however the new password created through these steps did not work either.

I am at a loss as to what is happening. Is it possible my account information is not being saved correctly to the database? Any ideas?
