AI Agent stuck with "Credit balance is too low" despite 400 credits assigned

I am trying to use the AI Agent (Beta) on my project "SolarFlow CRM." My Account page clearly shows 400 credits assigned to this project under Personal Test Pilot Credits (screenshot attached), and my paid Basic plan subscription is active.

However, whenever I send a message to the AI Agent, it fails with:

"Credit balance is too low"

And on retry, it shows a more detailed error:

"ACP turn failed: JsonRpcRequestException(-32603, Internal error, {message: Credit balance is too low, errorKind: billing_error, apiErrorStatus: 400})"

This appears to be a sync issue between my actual credit balance and what the AI Agent backend is reading, since the credits are clearly available and assigned on my account page. This is completely blocking my project development.
