Theme

Expected behavior

Login should be successful. When logging in using the same theme from the Shopify URL, everything works as expected.

Actual behavior

When logging in to the customer account using http://127.0.0.1:9292 a Shopify error page is shown. This only happens using the CLI preview URL, when using the Theme Access app with a theme environment set up with shopify.theme.toml. Not using the environment flag and logging in via partners account seems to work fine.

Verbose output

Reproduction steps

1. Set up store access with Theme Access app

[environments.dev]
theme = "123456789"
store = "my-store"
password  = "shptka_123456"
ignore = ["templates/*.json", "config/*.json", "locales/*.json"]

4. Run shopify theme dev --environment dev
5. Navigate to http://127.0.0.1:9292/account/login and attempt to log in
6. See following error:

@nboliver-ventureweb thanks for getting in touch! You can't log in via the login button when previewing locally; instead you need to use the store password.

Please confirm this solves your difficulty.

Thank you for reporting this, @nboliver-ventureweb!

Could you please confirm that this issue doesn't occur when you authenticate in the store without the --password flag? This information will help us in understanding the root cause of the issue.

Thanks again for reporting this!

@karreiro When authenticating with the --password flag (using the password provided by the Theme Access app), the issue also occurs. So, regardless of whether the password flag is passed via the .toml file or the CLI command, customer login doesn't work. When authenticating via the partners account (ie. no password flag), it works properly. Let me know if you need me to provide more context. Thanks!
