no_executor_available
What happened
Checking an indicator, and the assistant that builds one, run only on Forge's hosted machines. When none has reported in recently, the request is refused with 503 before anything is reserved, so nothing is charged.
What to do
Try again shortly. Check the status page if it lasts.

{
"error": "Forge indicator building is not available right now \u2014 nothing has been charged.",
