Remix app pim Integration deployed on fly.io

[GlennAppsal]

I am creating an app that integrates a pim system through their api with a Shopify store. It’s a one way import from pim to Shopify with auto sync. I’m partly finished and it’s working fine in development. I have deployed the app to fly.io 

when I run an import I get an invalid session error. If I click import again it normally works on second or third click. Anyone know how to fix this? I have not changed any settings regarding database or proxy. It’s just from the default remix template. Here is the error: │ [shopify-app/INFO] Authenticating admin request

Hi @GlennAppsal 

1. Have you tried reinstalling the app in the store?
2. If you don't want to try reinstalling, can you migrate the session data from the development environment to the fly.io environment together, what database are you using? You can find it in the session table of the database.

Have not tried to reinstall it. I am just using the SQLite default configuration that was setup in the scaffolded app. Do I need to setup a custom database for production? I’m not sure how the session work in remix

Can you check the session table in the sqllite data in fly.io.
