Hi there,
Thanks for providing the full error details including Request ID.
Can you retry shopify app dev and share the error information?
Can you also share with me the type of extension that you created at step 2?

step 2: I using payment offsite extension
Thanks for sharing!
Can you confirm if you are approved for payments?
Maybe it’s not approved. I follow this doc and can’t see the any requirement for approved. Could you please give me the steps to run the dev Shopify, Build an offsite payments extension with Shopify CLI

Payment extensions can only be built by approved partners, this programme is currently invitation only.
Thanks for your answer. I’m clear it now.
I have one more question. Do we have any way for development testing by installing my extension app, instead Published app. I need to develop and test some API before submitting app
At the moment you need to be granted permission before you can build a payment extension.

Could you please give me the flow or steps to grant permission
Permission is granted by invitation only right now.
We will open for applications in the future.
Here is more information on that process:

The steps should be
Generate payment extension
Deploy release extension
Submit release for review app
After approved I can continue to working, install/active app for payment
Please confirm or correct me if have any wrong
Currently it is:
Get invited to use Payment Apps API
Partner submits application
We review application
If approved, access to build payment extension is granted
Payment extension is built
Submit app for review
We review app
If approved, app can be launched
This process may change as the Payment Apps API evolves. But the above is the current process at the moment.

In step 4 I assume only app approved can select payment extension like offsite is it correct?
We allow generation, but only approved Partners can run shopify app dev and shopify app deploy in the Shopify CLI while a payment extension exists in the app.

Paige-Shopify:
approved Partners
how can check approved Partners or not please give me step
I can do that for you now
I will send a DM to you to ask for your Partner Organization information.
Sharing for context in case other Payment Partners encounter the same issue.
The Partner found that the solution was to run the following command:
shopify app dev --tunnel-url <tunnel>
The command needed that flag since their payment extension was using a tunnel.
I am also getting the same error in my remix app
