tier_required
What happened
Running Forge is open to every plan and is paid for in credits. Some features sit on the Paid plan, such as the verdict with its ten checks and pass or fail, and the strategy decay evidence. A route for one of those answers 403 with this code. The reply names the plan it needs in required_tier and yours in current_tier, and upgrade_url is the address of the plan page.
What to do
Move to the Paid plan, or leave that feature out of what you ask for.
Example
json
{
"error": "This feature requires the Paid plan.",
"code": "tier_required",
"required_tier": "paid",
"current_tier": "starter"
}The reply also carries upgrade_url, left out of this sample.
