• "Stripe: You need to agree first!" - your account is still in direct mode. Click the Agree button on the Connect page, then click Connect again.
• "Stripe: Invalid Reseller!" - the kitchen location behind the button could not be found (for example it was deleted or deactivated while the page was open). Reload the Connect page and try again; if it persists, contact support.

Errors are shown in a red banner at the top of the Connect page; a green Done! banner appears when the onboarding round-trip succeeds.
