bad_request

HTTP status: 400 Bad Request

The request was well-formed but a rule refused it. This is a different error from validation_failed, which reports specific invalid fields, malformed JSON and fields of the wrong JSON type included.

Common causes

• A variation key that already exists on the flag.
• A Boolean flag variation whose value isn’t true or false. Use a String, Number or Json flag for other values.
• A write to an archived flag.
• A malformed pagination cursor.
• An If-Match header on a write that can’t evaluate it. Only GETs and the conditional writes accept one, so remove it or send If-Match: *.

How to fix

• Read message, which names the rule the request broke.
• Pass pagination cursors back exactly as received.
