CHW-4607 ProxyInvalidConfig
proxy update payload failed validation; check remote_url, cache_negative_ttl_seconds, and that at least one mutable field is supplied
Default message: proxy update payload failed validation; check remote_url, cache_negative_ttl_seconds, and that at least one mutable field is supplied
HTTP status:400(client)
Problem. A PATCH /api/proxies/:name body failed validation.
Cause. The body had an unparseable remote_url, a non-positive
cache_negative_ttl_seconds, or no mutable fields. Fix. Inspect
fields.field to see which key triggered the error and resubmit with a
valid value. HTTP 400.
